The claim that the Bible explains creation does not stand up too well to experiment in this regard.
How can you experiment human origin?
And this single god is the consolidated version of all the deities that had come before then and understandably it's a deity that loves violence and has little to no mercy to those who oppose it. You wouldn't expect people who were oppressed for centuries to create a god that has never-ending love for all humans.
God is an extension of human consciousness that replaces conscience. It's a way to easily delegate responsibilities and defer wrongdoings. It's there so you can contain compartmentalized conflicting thoughts in your head so you don't go insane. You have your god because you can't tell right from wrong. It's like a tick that's attached to your skull and feeds off of your thoughts. Obviously like with any other tick, it's hard to rid of it.
People start believing stories made by <prophet/whomever> and they become facts all of a sudden.
I don't believe in that stuff. But it's a much more cohesive story than believing in an actual Adam and Eve with people living hundreds of years old.
If it happened, science may eventually prove it. Since you believe it to be fact, you should instead, push to dig deeper.
