This is a pretty good point... it's the exact reason why the creationist/evolutionist debate is an absolute yawn...
It's why 'faith' is the essential ingredient of any belief system... "Faith is the substance of things hoped for, the evidence of things not seen."
When it all comes down to it, there is no evidence to prove any truth... it all hinges on the individual to believe something he's not quite sure about! Quite an exciting gamble and adventure...
