I always hated != proofs - tends to result in some confusion.
I don't believe you can prove non-existence.
By experience: the god of the bible ... not the slightest trace of a godly force or influence can be found in any nature's law that was discovered so far by scientists, or in any period of human history that was reconstructed so far by historians or archeologists, ...
This presupposes several things that aren't necessarily true. First, that our science, historians and archeologists have discovered enough key truths in their fields; that these discovered facts are germane to our ability to determine the existence of God and that they have actually been applied to the process in any substantive way. Personally I think you could plug 'hairdressers, policeman and chefs' into your contention and it wouldn't increase - or decrease- the possibility of your statement being true. I'm not sure that science has the tools to prove God's existence - and I'm reasonably certain that we don't know enough to disprove it.
