Look, it's just logic. God could NOT control everything, if he could then we would be unable to have free will. It may sound like nonsense to you but it's logic to me.
Now another point. I'm bad at explaining things. Always have been, probably always will be, but I'll try to explain evolution to you as simply as possible.
Question One: Heredity exists, right? (this is a rhetorical question)
Question Two: Natural selection (survival of the fittest) occurs, right?
Question Three: Mutations happen, right?
Question Four: If natural selection occurs, would it not weed out the harmful mutations if mutations happen?
Question Five: If harmful mutations are weeded out, this would leave only harmless and even helpful mutations, right?
Question Six: If heredity exists, would it not allow these helpful mutations to be inherited?
Question Seven: If these helpful mutations are inherited, would it not be possible that they'd change the appearance of a species over time, perhaps even making a new species?
If you answered all of these questions "yes", you pretty much said that evolution is real. If you answered any of these questions "no", then I think that you should know that it has been observed in nature, though this may be just that "'scientists' pushing evolution are just trying to make a name for themselves by selling lectures and books", as you put it, though Darwin WAS actually a christian, I must point out.
