Have you read or heard about the Raelians? This is a religion, and atheistic religion. They don’t believe in gods (aliens created us) but still have a book that comes from beyond the stars that explains their beliefs (aliens need an embassy for example) as well as a messenger (known as prophets in other religious circles).
Is such a movement an accurate description of reality? Are there any facts to support any of their claims? Simple answer: No. Lets say we take out the beliefs that have no evidence for them. What do we end up with? Not raelianism. Maybe just plain atheism which is not a belief but a lack of such.
