God cannot be proven to exist, nor proven to not exist. Let alone the Christian God.

Proof helps to prove and ensure your claim of God existing, leading to your claim being more valid.

If you want to convince people of something, evidence and logic help. What's bad about proof?

Some people do want to convince people who don't believe that God exists though.

Christian preachers?

I don't care if people want to be religious, I have a problem with people trying to convert others with no good reasoning or logic, indoctrinating their children, and justifying their opinions on politics based off a religion that has no validation of being correct.

I want children to have the free choice of religion without being influenced.

It isn't flat
