name 1 thing not based on a belief.
for example (outrageous one at that but hey) Rachel Weisz is one of the 5 hottest women on the planet.
now click click bonga click from zimbabwe would say no, because she does not have 2 yard wide "child birthing" hips... but i still believe it to be true.
we all believe things to be true, but is there anything that can be proven to a fact?
even mathematical ideals can not be proven by the nature of math. there is no end to the numbers. you can never test them all.
oh well have at it
