That is pretty disingenuous since atheism is not "the idea there is no deity" atheism is simply the lack or absence of belief.
Admit? Who on earth ever suggested human reasoning could be infallible, this is just a straw man you've created. The reason your flawed reasoning is so obviously weak, is because it is demonstrably irrational, I've pointed out several logical fallacies you keep using, and you've rolled passed this fact without bothering to even acknowledge it. So you obvioysly don't care that that your reasoning is irrational, but that nonetheless means anyone who understands this, will not accept such claims. Like your constant appeal to authority fallacies, since your prophet was human, ipso facto his reasoning cannot be infallible, by your own admission, not without using a special pleading fallacy, which you also have used, and another poster pointed out to you.
Without wishing to be rude or unkind you don't have even the most basic grasp of how to analyse claims rationally, and it's clear you don't care, as all you need do is learn what these fallacies are and what they mean.
Leave aside theistic belief, the fact is you have never learned to reason critically, if you had you'd see how risible many of your claims are, but then I suppose that's a strong motive for remaining ignorant of the most basic logical principles. To preserve a single belief you obviously are emotionally invested in.
There is no belief I wouldn't relinquish if sufficient objective evidence demonstrated it was false. There is no belief I am 100% certain of, I don't even believe that is epistemologically possible. There is no belief I would hold on faith, and no belief I would treat any differently than any other claim.
You quite demonstrably can't say the same. I understand human reason must necessarily be fallible, you don't, as you keep insisting a human's reasoning is an infallible message from a deity, without any objective evidence and that is a special pleading fallacy.
