Lets suppose that i take a step in a random direction each time. And if is some moment i end in a city, I say that the path was predestined from the beginning to end in that particular city. It could ended in another city (and the same conclusion, with that different city, would had been reached) or never end in any city (and noone will ask that question). But the path taken was random, is the observer the one that put the meaning on it at the end of the path.

Because we're the flavor of life that is suited to this universe. If the universe were different, life would be different (but they'd eventually ask the same question). The question gets it backwards.

Wasn't it Voltaire who remarked about how amazing it is that the nose is just the right shape to hold up one's glasses?
