Guess I'll chime in since I finally got some time!

I'm a Naturalistic Pagan. When I began I did consider following either the Ancient Egyptian, Greek or Roman gods as I've always had an interest love for them since I was a kid learning history and mythology. That being said I know some pagans don't care for or count non-theists in their ranks, and as I don't believe in the existence of gods anyway, I opt'd to use a purposely fictional pantheon instead of one any typical pagans would have a connection to.

As philosophy wise the ideas of cosmicism and optimistic nihilism fit me to a 'T', my pantheon is the Old Ones from the works of Lovecraft. (Which ended up being funny as I didn't wanna 'copying' one community and ended up finding another existing community cause there's lots of us lol).
