A Crisis of Faith: Vol. IV?

"I do not feel obliged to believe that the same God who has endowed us with sense, reason, and intellect has intended us to forgo their use."
-Galileo Galilei

Never before has a quote rung so true for me. If there is a God (which is a subject of much inner debate at this point in my life), first and foremost, I cannot believe that he would endow mankind with the sole ability among all of the animal kingdom to reason outside of emotions and instinct, and then require us to forsake that ability to know him. I've heard plenty of times that God transcends "human logic," and thus, certain aspects of his being (such as the concept of the trinity, the paradoxical three omni's, the idea of a six-day creation that--whoops--rendered the universe to look like it's billions of years old, etc.) must be taken on faith despite the fact that they contradict our understanding and reason. Bullshit. This is the way I see it:

If humans evolved without a personal creator, it's a lot easier to buy that our ability to reason isn't whole, or is untrustworthy. To oversimplify things, our brains are basically made up of two parts. An inner section, which is where our emotions and instincts reside, and the outer, more complex cortexes of the brain, where our ability to reason comes from. The inner section evolved much earlier than the outer sections. Darwin teaches us that each evolutionary development is a mechanism of individual and collective survival. Millions of years ago (and still today, to a large degree), that meant being emotionally (read: morally) opposed to the idea of killing and eating our fellow man. Thousands of years ago (and still today, to a large degree), it meant belief in an afterlife to ease our anxiousness over death. The sect of thought that trusts so strongly in reason and logic (skepticism) is the same sect which believes that objective morality does not exist and the afterlife is a grand myth. Why do we, then, trust so strongly in our ability to reason? After all, it is a product of the same force (evolution by natural selection) which caused us to develop a sense of morality and believe in the supernatural in the first place.

On the other hand, there is the possibility that we are, indeed, the product of a personal creator, who has "endowed us with sense, reason, and intellect." This God is the creator of everything and is sovereign over the universe. And yet, it is this group of thinkers, not the former group, which believes that we must cast aside reason and logic to accept the truth of a God who is so powerful that he transcends logic. So, what, he intentionally made is with fucked up brains that don't reason correctly? Why? For kicks and giggles?

Neither of these ideas satisfy me fully. If there is no God and we evolved over millions of years by means of good ol' natural selection, I see very little reason to trust in my own ability to reason. If God does, indeed, exist, and is the creator of me and my brain, I see very little reason not to trust in my own ability to reason. Ahh, the irony.

If I'm going to continue being an atheist, I'm going to need a reason to trust in my concept of logic. If I'm going to believe in God, I'm going to need a logical reason to do so, and furthermore, a concept of God which does not contradict logic.
