Offshoots

"What do you think life beyond our Earth would look like?" "Considering there are zillions of planets out there, I think there exist mathematical probabilities that there could be repetitions of shapes that occur on our Earth." "I see what you mean: bird-like things, fish-like things, and so on..." "Yeah, they could evolve in parallel, or they could be offshoots of panspermia, but that's another class for you!"

The Abrahamic religions are offshoots of the Sumerian mythology.
