How do you prove a negative? How can you disprove something that only has resonance because of "faith"?
You've got it backwards.... Again, it's for someone setting forth the hypothesis to prove... not the other way around.
Theories have consistently been proven wrong in science, pretending that it doesn't happen simply is another attempt at misdirection.
One can prove that something didn't happen rather easily if evidence points in a different direction. You made one attempt at that with the 6,000 years thing. However your "theory" at that point didn't factor in the power of the Protagonist in the Creation story... Therefore your "evidence" wasn't strong enough for the proof that you asserted it was...
Let's say that one cannot prove that something is false... That means the Earth is the Center of the Solar System, right? The Earth is also still amazingly flat.
