You don't get to call it a belief when there's enough verifiable evidence to show that it actually does happen as a matter of fact. The theory of evolution might be shaky, and even then not as shaky as people with your agenda seem to think. But evolution as an observable phenomenon happens, as a fact.
Also: There's evidence for it. But there isn't evidence for your claims. The burden of proof is entirely upon you if you make empty unsubstantiated claims. Evolution is to a very large degree substantiated no matter how hard you try to believe it isn't.
You might have different ways into absorbing said facts into your beliefs, but you can't get around them by hand-waving and imagining that those facts don't exist.
/E: Let's do the rest of your post too.
Firstly, it's only over your head if you don't understand it. Second: Everyone's entitled to an opinion. It's just that some peoples' opinions are more informed than others'. You don't need to be an evolutionary scientist to understand it, but being one is obviously a good plus... That being said: They say evolution isn't a belief.
