But if they did, would you then suddenly be a different person? If the atoms making up your DNA were replaced on a daily basis, would you THEN be a different human? The point is that there are obviously some properties of things and objects that transcend the realm of the physical and, as long as they continue to apply to the physical human they are tied to, the exact physical makeup of that human does not matter.

As with most things, the issue over Ship of Theseus is mostly a words problem. My arm is the same arm I was born with as far as I am concerned, the question over whether it being of a different physical makeup makes it a different arm is so incredibly far removed from anything resembling a meaningful or reality-based conversation that it is absolutely pointless to talk about. If one day you found out that you were not the son of your mother but were indeed artificially bred in an incubator - would that make you a different human? Surely you would feel like you were different from what you thought you were but essentially you are still the same human being and retain all of the qualities you previously had, just with a different context than what you had originally presumed to be true. This is the core of the problem - “being” a human is a thought in monkey brains. People attribute different things to “being a human”. For one a new human might start and end where for someone else there have already been three different humans - not because there have actually been different humans, but because their perception of what makes a human a human is different. REALITY only knows the presence or absence of atoms, things like “being” or “continuing to be” and “ceasing to be” are ridiculed on this level. Down here, the only thing that “is” is math.²⁾
