We must take the existence of the world on faith. All we can know for certain is that which we experience directly, without use of our fallible senses -- i.e. our own existence. Cogito, ergo sum.

You might think that. I think that's a bunch of philosophy. I avoided philosophy (successfully) through 12 years of college (sociology and economics too).

I prefer science; that is, fact and theory.

Goodnight.

Sorry, but your attempt to kid your way around the thorny issues of epistomology has failed. One cannot talk meaningfully about "fact" without defining fact, and how one can distiguish fact from non-fact. Until one deals with the basic questions of Being and the nature of human knowledge, "science" is just another belief system.
