What is so complicated about this? You can believe in any wacky thing you want--just don't claim it's the truth, unless you can prove it. Which you can't.

But good beliefs cause and inspire men/women to do good things with their life and for others.

PROVE IT. And prove that people who don't believe in invisible deities don't do good things.

Some things need not be seen to know of their existence. I have never seen a Zebra but others have told me they exist and I know they do BECAUSE I believe what they say. same thing here.
