Evolution, or any scientific theory for that matter, is based on evidence. So claiming some sort of superiority is meaningless imo.
We all have our reasons why we do the things we do. When it comes right down to it;
reason itself is the issue. Some say God is the reason. Some say Nature is the reason. Some say there is no reason, and some even say there need not be a reason.
Somewhere in that spectrum am I. I happen to like thinking there is a reason for existence but would be hard pressed to provide what or how that could be possible. Existential crisis anyone?
