I'm not sharing my philosophy or religion just making points
It's one thing to be an atheist in the real world, since to be real any would-be God hasn't spoke to a group of people in ages. So I can see there point. But in the comicverse there's alot of people who doubt the existance of gods when Gods and Demons alike visit the Earth casually. I mean I would hate to live in the Marvel universe since Norse and Olympian gods coexist and visit the earth all the time, realistically there would be so many wars. Wouldn't that make all the Christians in the Marvel or DC world question there religion when they witness another one in action.
Now off the comics, I am going to talk about Family Guy (The MacFarlanverse), God, Jesus, Vishnu and all those other gods seem to make casually visits and contact with Earth yet there is alot of atheist. Now it's pointless to question the continuity of a comedy, esp. from Seth Macfarlane. Not to mention the same thing goes on in South Park... well I'll leave that one to you.
