Amongst others from here

There are several creation stories in Egypt, attached to rival gods. The most common one begins with Nun, the primeval ocean, from which Amen rises in splendour. He takes the name Re, thus in effect merging two rival deities. By an act of masturbation (described as such in the temple texts) he produces a divine son and daughter. These two breed a race of gods, while the tears of Amen-Re become mankind - appropriately enough, for man's behaviour soon persuades the creator to withdraw from earthly affairs. He retires to the heavens, where he reigns as the sun.

I don't believe this. Nor do I believe in the Flying Spaghetti Monster or the Invisible Pink Unicorn. Does that make me a "fundamentalist nonbeliever" or is that only lack of belief in specific creation myths?
