Being revived from death, perhaps in another person's body.
All humans fall under the subset of the species Homo sapiens.
Yet every human is technically unique.
That is already technically true even without the concept of reincarnation.
Well, then, I do not see that idea provide any "solution" to death/reincarnation in any way.
Let's say there is Microsoft Computer A, and after Microsoft Computer A seizes to function later there is a model Microsoft Computer B, that operates under the same hardware, and fall into the hardware of Microsoft Computers, yet they are unique, and also never co-existed, and is not influenced by A, so there is a lack of evidence to show that A is related to B other than their structure.
Again, humans are a subset of homo sapiens.
Yet most humans have no relation to each other, other than the species and by extension their biology, especially for those that never co-existed at a specific time. Ironically, this is why I think technically, a disproof is not possible. But the simplest explanation is that the soul, or something else, of a corpse won't be reincarnated into another homo sapien
As, scientifically, it is PHYSICAL DEATH we are talking about, where everything ceases to function by its definition, and having literally anything associated with the corpse "reincarnate" would break the definition itself.
Honestly, this is a ridiculous clame, borderline Theistic even though Buddhism has no Gods. This sounds incredibly crazy, and the more crazy it sounds, the less likely it is to be (Occam's Razor), so I disagree so much.
