None of this is in evidence. What do you mean by “me controlling my thoughts”? Libertarian free will is an incoherent concept, not just one without evidence. What you have there is an empty assertion, I’m afraid. Nor, even if you somehow control your thoughts through some kind of magic, immaterial process, that’s not a reason to trust them.
I’m afraid we can’t see that. You merely assume what you want to prove, that reason can’t arise from physical processes, and the typing monkey analogy does not help.
Why?
How do you know God has such an interest? And can we not establish that our perception of reality isn’t all that clear? Consider the analogy of your visual system, which uses all sorts of heuristics and shortcuts that render it vulnerable to optical illusions. That’s just the sort of thing we might expect in an evolved system, and we see analogous failures in human reasoning.
