Sure. Why not? They seemed to satisfy the needs of the cultures that created them. It's all the same. Well, if all gods are the same what is that you dislike about our culture that makes you hot to remove our's?
Imagine, though...a religion that executes non-believers. What a thought! A deity with the power to justify wiping out whole cities...except for the wimmens, of course...they might come in handy.
Imagine a religion that tells us to love our neighbor and do unto others as they would unto you.

Me? I don't care if people believe in deities. It's irrelevant to me, since my culture is one which prohibits religious folks from forcing their beliefs on other folks.
Heck, I have friends of several religions. I recognize their belief and hope they're happy in it. My Christian friends have their beliefs (and boy is there a lot of variation there), and so do my Buddhist friends. I have one neighbor who's a Hindu and one who worships the naturism of the traditional Hmong culture. The Hindu always takes very good care of my leaf-blower when he borrows it, and the Hmong grandmother who lives two doors down makes absolutely delicious spring rolls. I mow her lawn and clear her sidewalks in the Winter.
Why should I care what deities they believe in? That doesn't affect my relationship with them, nor does my atheism affect their relationship with me. Such topics rarely come up.
So, I like our culture very much. It encourages people to believe as they wish. It's excellent.
