We're too fucking dumb to bother with probably. Even the evil conquering ones don't want to bother with this stinking planet.
Why havent aliens landed yet on earth?

They probably have, but they don't really give a fuck. The technological advances and energy that needs to be controlled for FTL travel(with the current understanding of physics) will pale in comparison to us. I think i read somewhere that for a single day long warp to Proxima Centauri from here needs enough energy to push Jupiter from it's orbit. When you begin to consider just what types of beings and societies could pull it off without nuking themselves from existence then it's reasonable to conclude that we are worth less than shit to them, outside of scientific curiosity.(If they even have something like that) It's actually quite arrogant to assume that they would be hostile to us for any reason, they would need literally nothing materialistic from us.

If Aliens ever visited us, they'd be so technologically advanced and ahead of us that they could build their own robot slaves.
And why would they take over? For resources? Any resource on Earth can be found anywhere else in the galaxy -- hell, in this solar system -- in quantities 100x what they'd find here.
"I'm going to forcibly take those ice cubes from that gang of extremely violent thugs, instead of getting all I need from that frozen lake over there."
Best explanation so far.

lets say there are 1 advanced civilization per galaxy.....how in the hell will we meet eachother? Just visiting the nearest solar system seems impossible, let alone another galaxy

Wormhole near Saturn?
For us. We don't know what minerals and fuels exist outside of our immediate vicinity in space.
Also most of our fuel is used spent getting out of earths gravity. No reason why life couldn't exist who live on a planet with much lower gravity so that isn't necessary. Or they could have space platforms which is really what our species should work on doing rather than waging war amongst itself.

verses yes, dimensions no (at least it doesn't look that way)
i guess the question works either way, assuming a universe can escape itself
I don't understand this line of thinking. Us humans are still fascinated with lower creatures of all kinds for the scientific value they can give us. If an alien civilization was ultra evolved beyond our comprehension, they would therefore be advanced enough to know human intelligence has scientific value to be studied, and if they experienced fascination as an emotion then they would have to view us with the same fascination as we view the intelligence of octopuses, crows, or other great apes.
Secondly, let's not sell Earth short. This is a prime piece of real estate, with a magnetosphere that shields it from radiation, and has a biosphere that gives it an aesthetic far beyond the vast majority of dead planets. Go to Best Buy and watch the Brazilian rainforest on an $8,000 4K t.v., and imagine an alien species wanting to discover all of that for the first time.
Yeah, I guess multiverse is more correct than dimensions. It's all theoretical of course, but if we can assume that FTL travel is possible, why not the ability to 'break through' to another universe?
Maybe they have other food sources for now.
If you really think humans are the only intelligent life out of the TRILLIONS of stars in known universe, then all I can say is LOL.
It's likely that they just haven't found us and if they have, they may not have a way of getting here or contacting us. Or maybe they just don't care.

I'm just saying that it could he a real possibility that traveling space is impossible unless you want to make a ship that's the size of basically New York and tell everyone going they will never see earth again cause the point of that ship is to create a new society of humans apart from earth.

Because aliens do not exist. Alot of wacky folks want them to be real but if it was true then we should of already seen them already if they are so advanced all.

We are aliens to someone else, why haven't they seen us?
Nah they do.
Might not have been here but there must be something else out there.
We are in a galaxy of 300,000,000,000 stars. Just to go from one side to the other would take about 100,000 years at the speed of light.
There are possibly 100,000,000,000 galaxies in the universe.
The nearest spiral galaxy (like our own) to us of those 100 billion galaxies is Andromeda, which would take 2.5 million years to travel to at the speed of light. It has maybe 1,000,000,000,000 stars in it.
All it would take is for the only other living thing in existence to be somewhere in Andromeda and the chances of us ever ever ever ever knowing they existed is infinitesimally small, because the distance to cross a galaxy is minute compared to the distance between galaxies.
They could have worked out how to explore every inch of their own galaxy but still never ever ever ever know a thing about it.
The idea that if intelligent life exists that we surely would have been contacted is nuts when you consider the size of everything.
We can't even send people to the nearest rock that isn't in orbit around US! There is no doubt that any being capable of exploring their own solar system in person in a reasonable time span (say 10 years for giggles), would appear to us as ridiculously advanced.
My two favourite theories
Either there really is no way to travel faster than the speed of light, no matter how advanced a race gets. While this is plenty fast to travel around your own solar system, it's not enough for interstellar travel.
Or either that each civilsation is destinated to destroy itself before it reaches interstellar technology level. Just look at us, we're still a looooong way from Star Trek and our planet is already reaching boiling point.

Maybe:
Earth ain't that special.
There's too much space and hazard between stars for it to be worth it, for even nearby aliens.
There aren't any nearby aliens. Maybe there were or there will be in millions or billions, or trillions of years time, but we missed them.
There are no aliens.
We, the technological species we know of, have had such little impact on our own planetary system to be noticed.

I'm gonna read the post from ThoseDeafMutes later, but I personally think the vast separations have more to do with time than space.
It's already been noted that even at sub-light speeds, way more than enough time has already passed for some species somewhere to have evolved to the point of being able to explore this entire galaxy.
However, the OP said the Earth has been habitable for 250 million years (actually much longer). Modern humans have been around for just a few tens of thousands of years, and we've only been broadcasting and listening for barely even a century. I don't think it's so far-fetched to think some aliens could have come here millions or even a billion years ago when there were no humans to observe the event. I also think it's plausible that we simply haven't been listening for nearly enough time to find anybody. For all we know everyone else could be out there flying around at sub-light speeds and have just adjusted to life at a slower pace of time.

Perhaps I should have worded that better. My point being that if there is any chance of us ever contacting another intelligent race of beings, we would have been contacted by an intelligent race already, considering that Earth is 4.5 billion years old and will probably conk out in another 2.

That reminded of a movie but I can't think of the name.
Basically it was a mining ship or something and they find an artifact that evolves the humans in contact to get super powers or something. But the twist is
that it's actually some sort of weapon left behind to attract and destroy any civilizations advanced enough for interstellar space travel.
Anyone knows the name? I'm thinking trashy 90s movie (or maybe even series?)

Because the universe is immense. Let's say some advanced species have visited a total of 1 billion planets. The odds of them visiting us would still make lottery odds look good.
The way I see it: given the age of the universe, there HAS to be something out there that is at least on par with us.
The likelihood of there being NOTHING else out there is just...silly and I would believe we are a simulation before I would believe we are the only things out there.
That said, they are probably so far advanced beyond us...that it would just blow our minds. We likely wouldn't offer much to them, besides our fucked up planet and our sun, which isn't much.

I doubt it the universe has been around since its been around. Are you guys saying that in an infinite amount of time no thing has found out how to travel around space? Because i find that hard to believe. Even so there are an infinite amount of realities in all of them no thing has found out how to cross the line? I find that hard to believe.

Potentially for the same reasons we have not found or visited them yet. Or maybe they aren't even advanced, they could just be space yeast.

The idea that aliens don't exist simply because they haven't landed on our tiny spec of a planet which we have only inhabited for a blink in time, in the almost incalculable vastness and variety of the universe is hilarious.
It's a bit like saying Well I don't believe Natalie Portman exists, I mean, I've got a penis right here and for 30 years and she has never once called around to my house to have sex with me. Also, I've looked out the window a couple of times and I've never even seen her close to my house.

That's not true. We've seen Natalie Portman and know for a certain fact that she (or someone that looks like her...) exists.
Science can make predictions. The likelihood of intelligent life elsewhere is nearly 100%. Fermi paradox explains the possible answers as to why we do not have specific information about any given race having visited us. Its all a numbers game and is not really that much of a mystery for those who are confident in an answer. For me, its that the distances are insurmountable.
Tada

It is possible that we are the most advanced people in the universe and it is up to us to visit someone 
I love Fermi Paradox's treads.
That being said, there's one possibility that it has always intriged me:
Hedonism.
Consider that at some point, we can access to one infinite source of power. Say, cold fussion. Imagine that we can get a post-scarcity economy going. Nonexpensive Star Trek replicators for everyone! Why would we ever want to leave the planet then? Why colonizing the stars when we got all the shit we want right here? Why are your going to leave your wondrous utopia? For shit and giggles? Hell, people would stop working outright, nevermind about building spaceships and leading expeditions into the deep darkness of space.
If an alien civilization reaches a post-scarcity economy before developing faster than light spaceflight, it will loose the biggest incentive for technologic development: necessity. They will live happily ever after inside their wondrous dyson-spheres cum holodromes or whatever they have being able to build in order to solve their problems and pleasure theirselves, with zero fucks to give for the untamed, non-utopian rest of the universe.

I like the possibility that we're the only race which has passed the great filter in the history of the universe.
It's a lot better than the possibility that we just haven't reached the great filter yet.

I firmly believe (tin foil hat, I guess, but this is my personal belief) that they have sent drones as representatives here to Earth, but have sent machines only. Not life forms. To me, The Tehran UFO incident of 1976, and the Japan Airlines Flight 1628 meet all the necessary requirements for credible extraterrestrial visits and contact with humans, but humans with extraterrestrial machines only. Initially I felt stronger about the JAL incident over Alaska, but after reading literally every 'official' word I could find online, resulting in about 3 weeks of reading in my spare time, I decided that the pilot's testimony is somewhat questionable because this wasn't the first time he'd reported seeing a UFO. I think the story is still extremely interesting (as skeptic's say) because of the very specific story told by both pilots, the radar data corroboration and the involvement of the military in a second sighting early the next year.Sightings by another commercial airliner and the military again corroborated their radar info - at least - depicting an impossibly fast and large object. That story, despite the possibly sketchy captain, still happened as far as I am concerned.
The Tehran one is just fucking insane to me. That's "the one" I can't get over and no matter what skeptical contradiction I've read (and fuck, I've tried so hard on this one to be convinced otherwise), I remain convinced that was a drone from another world, and it really messed up our machines when we tried to interact with it, to fire at it, and to study it.
I think their drones are conspicuous because they are life forms and are thus fallible. I think of it like a huge 6 foot 5 inch very overweight guy trying to slip quietly and contritely into a the back of a college lecture class. Upon opening the door he immediately attracts attention because he's a large person and can't be stealthy just by nature of his size. He continues to be sly and contrite, kind of ducking low - in that way we do when we're trying to sneak in late to a meeting or a class. He comes in, trying to be quiet - makes a lot of noise trying to squeeze into a seat - attracts more attention sits and mouth-breathes, gets even more attention. I feel like they don't realize their airborne craft are fucking huge compared to ours. As far as I've thought of it, when studying our planet they mistakenly looked at our oceangoing craft as a relative size, for the size of their drones. Ships, not planes. They knew they needed to be to not be too conspicuous and they got it kind of wrong. A flying object the size of an aircraft carrier is too big to quietly slip into our atmosphere. It's an oops on their part.
To answer your question, I think their drones do enough to evaluate the planet and they are only able to send observation craft. Very, very advanced drones. I don't think they've been able to defy Einstein yet, and their collective lifespan makes it possible to send drones that far, and wait that long, to hear back. But for some reason they can't send a live animal/being this far yet.
Because there's still the chance a rock might slam into it one day.
If humanity is going to survive beyond a few million years or whatever, we probably need to be living on more than one planet. Our chances and longevity increase even more if we actually manage to live in more than one solar system.

There is the possibility in the grand scheme of the timeline of the universe/reality, that we may be the early and the only first advanced/evolved species to exist so far. We may very be, the first. Interesting, There is the notion that because of this, civilisations to exist onwards are from our third rock from the sun, descendants of a space-faring civilisation. If the chance of civilization unrelated to humanity exists in the future, it's considered that we would be the first to explore the stars, and that civilizations unrelated to humanity have the chance still to occur, but many consider that WE are the first.
It leads to one of Prof. Brian Cox's stances, he believes that humanity is at this moment the only civilisation in the universe, where he made the statement of saying if an advanced civilisation existed before us and considering the age of the universe that at this point in time, they would have already explored most of it, including us. Whether they have remains unknown, they simply could have preferred not to interfere. This is is him saying we are the only civilisation, not the only life. A civilization/species as marvelous as humanity came to be in events we do not even fully understand that it's highly, highly unlikely it can happen elsewhere in the universe. Many well known/prominent astrophysicists highly disagree with him though.
Makes you think of what Arthur C. Clarke said, "Two possibilities exist: either we are alone in the universe or we are not. Both are equally terrifying".
It's difficult to believe when you look at the stars when you have the chance of no light pollution and ponder the idea that we are just it in this unmeasurable reality that our own intelligence cannot comprehend the true scale of what we're observing.
