Lets say that tomorow it will be proven that God doesn't exist , religion will fade ,

I think that it wouldn't do anything good! 
Well it is posible to lead the world in chaos but not something good will come out of it .

What do you base this assertion on, if anything?

You must believe some form of "religion is the source of morality and moral restraint" to make such a statement.

My thought would be that the world is not READY for religion to disappear at this time ... too many people, if you believe what they say about such matters, refrain from pillaging and rape and general mayhem only because of the fear of hellthreat.

Until more people have an actual ethical center within themselves and behave responsibly because they understand it's in their rational self interest to do good, to support social reciprocity and to recognize their shared connection with the rest of humanity, then I suppose we'll need to scare people into being good, and religion is a good way to do that.

The open question of course is whether religion is actually effective in that regard or people just THINK it is. Also, whether in the absence of prefabricated religious ideation, people can rise to the occasion and think through their OWN values for GOOD reasons.

I tend to think that most people who believe religion actually makes people better moral actors, have been conditioned to think of themselves as moral defectives via the doctrine of utter depravity. I think most people would not even be vulnerable to such nonsense if they didn't personally care about doing the Right Thing. So I conclude that the fear of moral implosion in the absence of religion is an unfounded fear.
