Well i consider myself a Christian who isnslowly returning to faith (cautiously to not overdo ut) so i'll try to answer the wuestions the best i can:
- You can't show the existence of God by requiring scientific proof, but we
believe there is, or for some might be, a force (not a person) who (that?) that could create all what we see and feel, or at least orchestrated the creation of life everywhere, or at least on our rock in space
- All in the book of Genesis. God loves us, gave us paradise and by eating the Forbidden Fruit we chose to decide our fate. He doesn't hate us because of what we did (as he did lay a path to redemption for all of us), but we are responsible for all our actions. God did try to meddle and reset everything, but after sending Jesus he does not interfere with our way of mortal life.
- God is loving, but more like a fatherly love where he want you to overcome your weaknesses yourself.
- etc.
We do have a hard wired need for religion and belief. It sits deep in our periaqueductal gray. Scans of our brains have shown higher activity in people who claimed to be religious and the more religious, the more movement in it. Belief is as natural as feeling pain, fear, love and altruism - all in one place
knowing that - can we call believers dumb?
