Has Science really destroyed God?

Why does the Human Race insist on trying to disprove the existence of God?  First there was Darwin, and his theories of evolution.  Then the scientists in Geneva who were trying to re-create The Big Bang.  Why are we so focused on the how, and not the why?  Why is no one trying to figure out WHY we are here, instead of HOW we got here?  When are we going to realise, that the Universe and everything in it, is just one big science experiment.  And guess who the Scientist is!
