People have believed in a God, not necessarily the same God, for millions of years man has been on the planet and they will believe until every last human is destroyed.
I don't think that is a reasonable assertion to make.
Religion is borne of ignorance and a need to imagine the answers to the questions of life, the universe and everything. Since the human species has begun to explore its reality by way of the scientific method of observation, measurement and testing, we have rapidly learned to better understand the cause-and-effect action/reaction processes that make up our universe and are growing increasingly aware of the fact that 'god did it' isn't knowledge of any kind.
Trouble I have with this, is science can never disprove God may exist. It's impossible to do.
Possibly science can disprove religion(s), such as the bible. But that's a different thing than disproving God.
To be fair if science can eventually prove the bible completely false, I wouldn't want to be around anyway, it would create lots of very very very angry people.
