Ok, you've touched on the Anthropic principle there, I stand with the weak Anthropic principle.
I'd also add, that it's impossible to disprove the existence of a God, in a vague and nebulous sense. But, does anyone actually believe in a God that way? Every major religion at least gives various details about their God/s, enough information that those specific ones can be disproven.
Welcome to the grey. Religious belief is nothing if not a broad swath of grey.
Example: fundamentalist Christians believe Eden is a real place, Adam and Eve were real people, a serpent enticed Eve with a literal apple, and from thus sprung all of humanity, and the burden of original sin we all carry. Less zealous believers understand the metaphors of the Bible, and believe its accounts might be based on less scientific understandings of natural events, or recountings by those of the more zealous nature simply written down by those like a detective who jots down (for the record) that a suspect said he ate his wife because the dog told him to do so.
Every major religion gives details about their god(s) that can be disproven on their face value; sure, I agree. But in the most honest moving of the goal posts, I'd simply argue disproving the easy "how" will never negate the bigger "HOW" where a god, God, or an intelligent intent might exist. That said, I dismiss people who suggest the bigger, unanswerable "HOW" somehow propagates downwards to validate the factual nature of the smaller "hows." Because I can't precisely articulate the Big Bang does not lend default credence to the story of creation in the book of Genesis; doing so would be basic logical fallacy. Conversely, if I were able to pinpoint beyond doubt the exact time and place of the beginning of the known universe using observable, verifiable, and peer-reviewed data, I cannot say without doubt that there wasn't a Thanos who snapped his fingers who started it all.
Hence my agnosticism. As long as we don't know who's got it right, anyone
could be right. Hell, we all find out eventually, don't we?
