Whoa, I said science has confirmed there is a positive correlation between prayer and positive health outcomes. That's it. The simple fact of the matter is science can neither prove nor disprove the existence of God. And, sure, what's remarkable to me may not be remarkable to you or anyone else, as far as canonized saints, or anything else for that matter, is concerned. However, just because people do not value it or believe any of it is meritorious, doesn't mean it lacks intrinsic value or validity. There was a point in time people believed the world was flat, but that doesn't mean that the truth of the world being round did not stand on its own merits.
The paradigm you are using to repudiate that logic and reasoning can be applied to a belief in God or a Higher Power is significantly flawed. For one, again, you assume the Calvinist viewpoint of God is the only one that is logical to construct an argument for an omnipotent, omniscient God. It also seems you believe the Bible teaches a Calvinist viewpoint--at least, that's my interpretation of one of the main cruxes of your anti-God rhetoric. Regardless, you are constructing the majority of your argument from the vantage point that God isn't real and proceeding from there--and since science can neither prove nor disprove the existence of God--the foundation of your argument is already significantly flawed to begin with.
Additionally, the other problem with your argument is you assume that God can not exist outside the bounds of time, space, and matter (which is a belief it seems Albert Einstein had, btw). You also assume God's motive or purpose in creating humanity. Well, and assuming God does exist for argument's sake, it seems quite apparent to me that God had two choices when creating human beings: 1) Make them into robots or 2) Make them with the capacity for logic and reasoning and give them the free will to choose right or wrong. Again, assuming there is a God, we can only speculate the reasons why God chose the latter. I believe because love is only valid when it is freely chosen is why God made us that way. For example, for me at least, I would rather be loved because my girlfriend chooses to love me, of her own free will and volition, and not because she is robotic and pre-wired and pre-programmed to do so. If she isn't given a choice, there's no real meaning behind her "love" for me, because it doesn't come from her own free will. Therefore, if God seeks the same type of authentic relationship with humanity, then clearly the only choice is to create imperfect human beings with the capacity to choose good or evil. And ultimately, free will has consequences and creates chaos.
Regardless, using the faults and limitations of mankind as evidence that a God or Higher Power is flawed and consequently must be concluded doesn't exist is at best circular reasoning. Because, again, you are constructing a significant part of your argument under the assumption an omnipotent, omniscient, perfect God would not create an imperfect, chaotic world and universe subject to many evolutionary principles. That is not proof. That is conjecture and again, at best, circular reasoning. It also erroneously assumes God has limitations as a result.
Look, I get it, it seems you are very ardently atheist. So I understand you will summarily disregard any notion that God might exist. That is certainly your right to do so. However, the greater point is that it is in fact more reflective of a hubris that you try to substantiate the belief in nothingness as being unequivocal in it's logic and merits in comparison to any sort of belief in the divine. In fact, it could be argued that you are more pretentious in your inexorable, unencumbered belief in nothingness in comparison to someone who believes God unequivocally does exist. Absolutely, religious fanaticism, insane interpretations of religious texts/scripture, dogma, etc., can, does, and has existed throughout human history. However, it takes a hell of a lot more faith to believe in nothingness than it does in something humanity will never be able to fully explain (God).
Beyond what I've written, I have nothing more to say on the matter. You're entitled to your beliefs, like anyone else. Good day.
