well although i don't agree with your examples, i don't believe things just happen randomly. If you actually pay attention to things going on in life, you see that certain events happen to prepare you for other things in life, I mean if you look at the people you know and how they have effected you, and that if they had not said one thing in your life, you would be a completely different person, that in itself is enough proof. but i also notice other things that are smaller.
