We have records of Chinese and Indian philosophy going back further than the Greeks, actually, Dyshade. Buddha and Confucius were both dead and ash before Socrates was ever born.

Derdy is actually right, even if her arguments aren't very eloquent. All evidence and logic indicates that philosophy is a natural aspect of the human condition. Once we get past the stage where we have enough to eat, we naturally start asking "Why?" Now, the Greeks were certainly influential to Western philosophy and theology for thousands of years to come, and they codified much, but to claim that without them philosophy would not exist is simply wrong.

Hell, the first written text we have, the Epic of Gilgamesh, is nothing if not a philosophical tale- What is life? What is love? What is friendship? Why do we struggle if all comes to nothing? Gilgamesh's struggle to obtain immortality, his noble quest where his prize is taken at the end by a snake as he sleeps, is as apt a metaphor for life as any that has been made in the four thousand years since. When he invites Urshanabi to look upon his city at the end of the tale, that is his answer; he's saying "I will die. My city will die. But once, this was here. Once, I was here." And this centuries before Troy was even built, much less destroyed.
