Superheroes, Religions and Gods - What's the difference?

Do you reckon Superheroes exists on the same reason as why religion and God exists? I know this is by no means a 'SMALL' question to ask, but I'm just wondering. Maybe.

I think the creation of superheroes may have been linked to the creation/beliefs of religion and God. All three have the capability to keep us level headed, responsible and moral citizens, but only working in different ways.

Very early heroes were not printed in glossy papers and published every week or month. Robin Hood, for example, is a character of folklore passed down from generation to generation. It is beside the point whether Robin Hood existed or not but rather how Robin Hood became a-someone who looked after the lower-class and whose morals and beliefs that the ‘average’ Joe/Jill could agree with.

The more familiar heroes such as Superman, Wonder Woman and The Avengers were created to also, prevail in a time of hardship. Many of the famous Golden Age superheroes were created during the time of the Great Depression and WWII. The comic superheroes took a stand for justice, freedom and ‘The American Way’, battling against Nazis, communists and the Axis. This definitely appealed to a range of audience because it did give readers a firm belief in someone or something that understood the needs of that dark time, the need of a hero. Kind of like how the belief in God keeps people sane and grounded in times of need, because God is their hero.
