More gods would make sense. I mean... none of us are born from masturbation. God needs to put his schlong in something too.





Jup... that oughtta offend at least one Christian. My work here is done. Super-atheist away!

Not according to some creation myths....

 

 

Speaking of myths..

Many Christians and Muslims downgrade other people's belief systems to a myth. At what point did they 'prove' that their own myth ascended above other myths?

Did someone 'stamp' some documents or what?
Seriously what happened?
