Simply put, we wouldn't exist. It is impossible to separate the creation myths of early civilizations from the people themselves. It was part of our evolutionary process to explain mysteries in the world with fantastical stories and binding them with morality issues to self-govern tribes and civilizations.
I may as well ask "where would we be without sentient thought?"
PS. I love all the people on this forum who blindly state "the world would be way better" because it's en vogue to hate on organized religion nowadays. Any rational examination of the situation would realize that simply isn't the case.
PPS. I despise organized religion in general but I'm not foolhardy enough to overlook some of the good it has done over the years (along with the bad, of course).
