I find it truly bizarre that Roddenberry being an Agnostic (I'll believe in God when there's proof, but, I won't dismiss the possibility of God's existence either without proof) would mandate all of Star Trek must be Atheist (God absolutely doesn't exist and anyone who believes in a God is a Moron).
There is so much more room for stories through an Agnostic lens then an Athiest one, why would an Agnostic mandate Atheism in Trek, if he won't even label himself as Atheist?

Where are we going? And why are we in this Handbasket?
