God doesn't exist
I don't believe in God because we can't see him or because we don't know for sure what happens when we die, I don't believe in him because it's like believing in folklore. The stories in the Bible are stories that have been passed down from generation to generation, adding new details and elements to either teach us a lesson or to entertain. We don't know what's the truth. For all we know the bible could've been written by a bunch of mentally ill people who believe they saw angels and heard animals talk. There's no actually evidence of God and heaven and angels besides story and it's in human nature to lie.
