And yet, it isn't. Kinda. I mean, there are really powerful Gods. Elder Gods. Like Gaea or Cytorrak. Beings that would literally blow guys like Hulk or whoever away like they were nothing. But then you got all these other lesser Gods, like Thor, Ares, Athena, and hell, you could throw Zeus and Odin in there too. I mean, they're powerful. Powerful enough to slap regular Superhero types around, but they pale in comparison to the Elder Gods. And those guys are probably chumps compared to the the Celestials or any of those other high end cosmic beings. Space Gods basically. There is some, universal, connection to them and all that, but it's not as big a deal as one might think....in the grand scheme of things. Remember, Science, Magic, all that stuff works within the universe. Why is it so hard to believe that a product of Science could trump a product of magic? They're both just different ways of creating somebody or something really powerful to punch the f**k outta something or whatever.
I always liked DC's explanation of Gods as dreams who gained sentience and draw their power from being worshiped.
