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 .

It is not up to the skeptic to disprove first off.

Secondly, while religion isn't going to go away, if it were not for countless humans in the past questioning social norms, our species never would have left the caves.

I think tons of good have come from questioning old mythology. Women can vote, slavery ended, even today, LGBT have far more rights in America than they did 40 years ago. 

I do however think theists fool themselves thinking that their religion will last forever. History is full of now dead religions. If our species doesn't kill itself off in 10,000 years we should expect to see the current ones still believed, morph into something unrecognizable in the future, and or completely die out, like Roman, Greek and Egyptian mythology.

Fear keeps people in religion, lack of fear of questioning leads humanity to better answers.
