Did ya ever think we were created at different locations on this planet out of slightly different types of clay? Seriously, if you are going through the trouble of seeding a planet, do you just create one thing in one place?
No, they believe in nothing. Everything just miraculously sprang into existence all by itself. Then life just miraculously sprang into existence all by itself. Then sentient beings slow cooked in the miracle soup for a long time, before miraculously springing into existence.
Freakin atheists sure do have a lot of faith.
Why would anyone think that? The evolutionist would reject it out of hand. The creationist would reject it on biblical and scientific grounds. The concept of original sin is lost if there is more than one Adam and Eve, and there is no need for more than 1 pair of initial ancestors to produce the (fairly limited) genetic diversity that we see today.
