I used "we evolved" in the sense that he used it so I could communicate with him; in actuality, I subscribe to the Selfish Gene hypothesis where "we" really don't matter at all. Our genes compete for survival against not surviving. They compete against each other inasmuch as they are in competition but otherwise they cooperate in the sense of accepting each other as part of the environment in which they propogate.

there is a direction and purpose to evolution, it's: replicate or cease to exist.
