Rationalization.
Suppositions. You assume too much, you presume too much. You're relying on logic too much. Religion isn't of the mind, it's of the heart, although most religion today is of the mind, too. Reason is of the mind.
But the fact is that he knew those things, they were part of his mind. Yes, you could make the case for an impersonal God, that he doesn't care about humanity. But, if you can think of God is being Life itself, there is no reason why He would need to care; being alive is enough, being alive is the proof. Eastern Religion says that we don't really know what Reality is, we only think we do. Eastern Religion says Enlightenment is always sudden, even if we think it is slow, say over many lifetimes, when it happens it is always sudden.What is Enlightenment? Seeing Reality.
Why don't you also question EVERY experience you have, then? Why do you accept everything the mind tells you? Why do you rely on logic so much? Logic has nothing to do with life. Biology has to do with life. You're born, you fall in love, you have children, you die. Love is not logical. It just is. It happens. No logic necessary. Relying on Science to tell you that what you feel isn't real will be seen as preposterous when one is in love. You will just laugh. Just like if Science says that there is nothing to sex, you will just laugh if you think it during sexual intercourse ...
It is only "clear" to you. Religious experiences are connected to God only because logic dictates that they are super natural, and therefore they cannot be real. Again, you are using the mind as the standard. All I can say is that I have had experiences which I KNOW were not manifestations, hallucinations or delusions of my mind. I KNOW they happened.
"Experiences are the result ... of our brains"? That's what Eastern Religion says to - that what we experience as reality is just an illusion of our mind. Of course what we experience is of our minds because it is the mind which tries to make sense of what we experience. But if we experience something which the mind cannot make sense of then our minds stop, our thinking stops. It is only afterwards that we rationalize it. If we are lucky we will see that we are aware that our minds are not thinking. Afterwards we cannot convince ourselves that what happened didn't happen because to do so is to negate consciousness itself. Yes, you can convince yourself that the brain had a fart but you cannot hope to convince yourself that you were aware that the brain was farting, certainly not whilst in the experience itself.
Quite the stretch isn't it? If it is just DNA, biology and evolution, then why not just accept it? Not the lunacy, of course, since that is also just logic at work.
No, the skeptic isn't supposed to accept anything, that's why they are called skeptics. You THINK that that is what others are expecting from you. God doesn't need to prove he exists just like love doesn't need to prove it exists. Can you prove you exist? Say that you are talking to someone with an Eastern Religion. They tell you that you do not exist, you only think that you exist. How do you prove it? You could slap them and say "If I didn't exist then who slapped you?" They will say that you did not slap them, that 'that' body struck 'this' body but "you" did not strike "me". It's just a different mindset. If you knew Reality then you would not speak like you do because you would have a different mindset - the Enlightened supposedly react, the mind is a slave, it has been mastered, it has been transcended; it responds to questions but the awareness is there that it is the mind that is answering, that they are awareness itself.
Faulty logic. Someone else would look at the panorama of life and see that as proof enough.YOU are trying to corner the theist, setting up the argument such that he cannot possibly win the argument. Minds playing mind games.
Astrophysicists don't know everything about the Universe. You are limiting your knowledge to what they know. You accept whatever Science says not realizing that what they are saying may not be true, it may just be a best guess. Consider Black Holes, Dark Matter, Dark Energy. Would you have believe in them 100 years ago when they were not known? But now we spout it as if we know what that means. Well there was plenty of things 100, 200, 500 years ago that were not true, but everyone thought that they were truth. Blacks came from apes? Today we know that it isn't true, but "we" believed it hundreds of years ago. Today Science says that Man came from Africa. But we don't think that we are Blacks, right? If we did we would not be prejudiced.
Unless one transcends the mind. Experiences and visions and feelings are insufficient to "You". Eastern Religion says that if you transcend the mind you will see that your position doesn't matter and will be seen as childish.
What you call "shaky ground" they call a rock. Faith is mental, a convenience of words.
You think that they are 'sticking their fingers in their ears.' It is your conclusion. That doesn't make it right. Appealing to logic won't help.
Where will your logic be when you are dying? You can be logical about death now, but you won't be logical about it when it is actually happening to you. (Any arguments you can proffer are mere imaginations.) Then you won't worry about the experience because you will be the experience itself. Religion deals with life and death. Neither is logical. It needn't be because it just is.

If they were thought interchangeable, then it would be easy for a Deist to become a Theist through direct experience of a "miracle". What form that miracle took can only be known to the Deist.

I'm not saying that Science is wrong. I am saying that whatever it says we accept as true/truth at the moment. The same can probably be said of Scripture - it is not wrong, it was accepted as true/truth at the moment.
