I think most atheists today believe in a god-like race of aliens who come from either space, the future or an alternate reality. They consider them mortal beings so that's why they aren't gods. Some still think that planet Nibiru is a real planet, and those beings created us. They will believe almost anything other than the God of the Bible. They don't want sin to exist. They want to be free to do as they deem best. They totally reject that "there is a way that seems right to a man, but the end thereof is the way of death".
I have never read or heard these ideas from any atheist, JTC. Atheists, by definition, don't believe in any type of gods, god-like beings or deities. Where do you get this information from?
