But the old testament, isn't it also part of the quran? It implies god has a form, for if you see his face you die or lose your sanity. (exactly like an eldritch abomination!)
Also there are many ways to argue for some being a black sheep, literally any and all differences could be made.
Also the truth doesn't care what its compared to. A truth is true regardless of who it sits next to. So it doesn't matter that it may or may not be a black sheep in regards to your faith's accuracy or inaccuracy.
Also there are alot of things a most powerful god could do aside from having a form that shows he is limited. Like, he chooses a flood, instead of instantly snapping his fingers and preventing all conflicts for all of eternity. Why would he want to create his own problem?
Its like an artist letting a dog tramp all over their floor painting before it dries, and pee on it, and let it prance around and prevent you from working at all. Anybody with half a brain would've isolated the dog before hand to prevent the problem. And the artist says, ya know what, the parts of the painting that I let get dirty from the dog, I will recreate them in a painting of the utmost agony! lol Besides, a god doesn't have a body, so he does not get stress hormones to cause anger. So even a humanized god disproves itself automatically by saying we are made in his image. Plus its incredibly narcissistic. Like of all the species on earth, we are the ones that god made us like, that's like being a demi-god compared to mortals or something.
I think the narcissism is more readily explained from humans overcoming the challenges of nature when moving out of nomadicism into sedentary lifestyles. And I understand that transition well enough for it to debunk any claims of god I have seen thus far. Literally aliens or god(s) or angels themselves etc would need to come down as evidence, and even then it might in the future be a projection or hologram from someone trolling. Or the aliens could claim to be gods or angels, and actually be lying. Etc etc etc. I looked at religions from each continent, and all seem the same aside from Darwinism and geographic restrictions and resources causing localized differences.
