Answer:
If there was no religion no one would have someone (for me God) to look up to the world would be complete chaos, because there is no right or wrong. And no crusades would happen because there is no religion. I believe people may be looking more for a king like it says in Old Testament bible times. My opinion people have came up with other gods because they don’t want to follow the one God. So they made other fake Idols. So no religion just maybe one or two kings in complete control.
