Ironically I have been an atheist longer than I have a Christian.

We muddle through with legal guidelines, reason, considering the circumstances, deliberating among ourselves. — Vera Mont

This is my point, the We is ambiguous because it would be the government that decided what is okay or not. Which in turn would create more North Koreas or another USSR. And yes those things happened, because if God does exist he is allowed to do anything he wants, we all disobeyed God and deserve hell, but he chose to save us that’s the beauty of the Old Testament. And the Old Testament wasn’t written for today it’s like saying Ancient Greece laws wouldn’t work today. God didn’t impose any debt, just as though a bank loans money doesn’t create the debt if the people can’t pay them back the loan.

Then enlighten me on what they think.

Concrete evidence does exist, and when questioning a God why wouldn't you be able to fight for that God with that book. In order to prove science, we don't stop people from using data.

For a few reasons, the biggest is that it is a new thing. For all of human history until the last century Atheism was seen as something that is false. Atheism fights a God they don't believe in. In doing so they replaced God with Science, and in doing so they don't have to worry about a higher power with higher morals.

I think the major problem with your thesis is that your putting your own beliefs and morals above Gods. God is a wrathful and judgmental God, he desired us to be loving because he will ultimately judge evil not us. God wages a Holy war, unto which we cannot do, so that we can receive rest from Evil. Some of the times we need to trust in God and know he's all-knowing.
