I think we can compare the two. Who knows? Maybe in another thousand years, Christianity, Islam, etc. will all be school subjects, sort of like Greek Mythology is?
Is it possible that religion changes drastically over the times?
I don't believe in that stuff .gods just somebody or who knows what out there. Did the Greeks ever see Zues have evidence for it? I don't know how it all started but we(some humans) just believe that.
