Think about it- through the millenia, why have different peoples from completely different backgrounds, livelihoods, times, and social status turned to God if He didn't exist?

The most popular religious affiliation in the most populous country today is "agnostic/atheist".

Also, many countries have certain religions because they were foisted upon them by crusaders hundreds of years ago.

Now, having said all of this, I have no problem with someone believing whatever religion they want, and I have no intention of trying to regulate someone's religion (as long as they aren't hurting others). Where I have a problem is when people want to use religion as the basis for law.
