I have a friend who I sometimes discuss these things with. He has exactly the same view as you here - traits being passed down to help the species survive. You know why its the same? Because this is what science says about it. And if you read science, you will believe the same things. Its not even your own thoughts.

I just find that interesting. But I also realize the same can be said for spirituality. If you ask someone what they believe, its always a carbon copy of what is popular to believe in those circles.
