And here I am recognising your post and replying to it. I guess I'm here thanks to the big-bang but this reply is more than that. It's the problem - consciousness, this ability to look inwards and question things to a degree you demonstrated in your post. But maybe I'm jumping the gun and should only be thinking here about how we got to be who we are. Destiny, God's will, biology! Combinations of those things. Are there any more possible reasons? I think that it is very improbable you will come to be the person you are at any time before your birth but once you are born, you can take it that it was always meant to be.

There was a lot of intention that went into computers. Our infrastructure is a result of humans looking for ways to communicate to each other. We wanted to fly, to understand our universe, to study other planets... That's all taken work; intention; cooperation; and quite a bit of resistence from life itself.

You'd never know. That's the reality.
