The issue with this argument, just as many others, is that while you cannot prove that it exists, you can´t prove that it doesn´t exist either, leaving it in a grey zone, kinda like with supermassive blackholes at the center of a galaxy, theoretically they should be there due the the radaiation and gravitational pull, though nobody can prove that they´re there, or not there for that matter, in that regard it could be just aswell a supermassive pink squirrel cought in it´s own gravity well, while god is something more obscure, it probably depends on how or what you define as a "god" theoretically it could also some all-powerful being that just roams this or any other dimension or non-dimension of your choice...and not giving afuck about anything, leaving the question of proof for and against open once more. The average human tries to explain things with rules and mechanism he sees as fundamental and unchangable, what people do forget about that, is that the humans view is just that, the humans view, it´s not absolute, while things might seem right from one perspective, they could be completely different from another simply because one of the idividuals cannot comprehend the views of the other. Conclusion once more, the human simply doesn´t know anything for sure, despite thinking so at times.
