What if Everyone was Atheist?

[abaris]

Well, not really "interesting" - more like "baseless" and "speculative".

We can't possibly know what the world would look like without religion, because we've never had an opportunity to witness such a world.

Oh, but you can make an educated guess by taking a close look at human nature. You can't possibly think that it's pink elephants and fairies floating from everyone's butthole, once religion is gone. Think again, and think about the people's need to feel exclusive by belonging to certain groups.

Well, maybe you're really that naive to believe human nature would change overnight.

How do you know what would "fill the void" wouldn't be better - as in less destructive and more open to evidence and reason?

Look at human nature and history. Do you think, it would change? Since you called my assumptions baseless, based on what other than assumptions?
