I've been on something of a spiritual sidequest irl the past couple of years. I'm not burning incense and climbing mountains to meditate or anything, just taking in perspectives and information and trying to form a personal viewpoint of the universe that satisfies my brain.
I think it's beyond obvious that there is, was, and will continue to be life elsewhere in the universe. It's a numbers game. The universe is huge. Like, unfathomably huge. Literally. The numbers that are calculated in the scale of stellar objects is beyond our flesh and blood capacity to comprehend. We know the numbers, we know the concept of the scale, but it's akin to a dog going outside to piss. The dog knows there's a larger world, but beyond barking at the moon, or the mailman, the dog has no reason or ability to interact with them, so it Goes back inside. It understands it's owner, his mood, where it's food and water is, where shelter is - but take the dog to the store and tell it to buy it's own groceries.
All that to say - in a space that is so vast that we've essentially turned it into a formula just to gain some facsimile of understanding regarding it - that one planet, one grain of sand on the beach - is the only host for life in the universe....
Basically impossible.
"with all our tools and technology in the 21st century, we should be capturing these things in 4k daily," - some dude, probably. Space is huge. It's expanding, things are constantly growing farther apart. Perhaps we're the hillbilly town of 150 in the middle of nowhere in the universe. Maybe ours is a cosmic road that's scarcely used. Maybe only one species is close enough to come by. Maybe the alien sightings that have photo/video attached are just the ones that are being jackasses or have faulty equipment, and generally, they're out buzzing about like bees over our heads and we never notice them.
I'm passing to the left, bros.
