OK Frank I can see where you are going and I think you are correct but I still think that we should consider this.
If we were to consider that a God really did have an interest in us all knowing that he existed, would it be unreasonable to think that he would be unable to put his words in all of our brains so that we all would agree that it was from him?
Okay, RL. But that contains an unnecessary qualifier...that there is a God that really has an interest in us all knowing that it exists.
What if there is a GOD...and the GOD had absolutely no interest whatever in whether we knew it existed or in anything else about us?
There are "religions" that posit exactly that. Deism is a form of such a religion…one that simply avoids or dismisses the notion of revelation of any sort other than conjecture. Those kinds of religions are not necessarily "wrong."
What I am implying is if you were a God and were able to make DNA and able to to make life as it is which is very complex, "couldn't you also be able to do something less complex such as add a hard drive so to speak into all of us so that we could all acknowledge it as being the absolute word of God without any misinterpretation so that we could all agree and he could also give us the free will to ignore it if we wanted to? Why would he have made us "to where we had to learn his word of truth when he could have implanted it in our brains and yet still gave us the freewill to use it?
There are all sorts of GODS that could be possible…and certainly a GOD that couldn’t care less about revelation is one. Another could be one that could not care less about what animals do (sets of morality)…and would, by default, give all animals including humans the “free will” to do whatever they thought appropriate.
If there were a god interested in revelation of self…I cannot conceive of the god doing what the gods that have been worshipped on Earth to date have done to reveal itself.
Anselm suggested that “God” is that which nothing greater than can be imagined. Anyone who cannot image a god better able to reveal its existence and its intentions than (for example) the god of Abraham…simply has no imagination.
RL, I suggest that perhaps the question of your title may be what is troubling me...not your arguments. I agree with the general thesis of your arguments...but the question as posed misses the mark in my opinion.
