Why does that matter? The point is that they are the same in one particular aspect, that of identity.
Again, I understand that people think this way, but is it true?
I am sure it is.
One has to
correctly understand the concept that is attached to the word "identity" before one can evaluate whether or not people are right.
Describing the concept of identity in exact detail isn't the most trivial task, but more importantly, I don think it's necessary for the topic at hand.

Not really. I'd say that the concept of identity prohibits the possibility of two different portions of space that occupy one and the same point in time to have one and the same identity. In order for two portions of space to have one and the same identity, they must be temporally separated.
Possibly everything has the same origin. Is a recycled can made of metals from different sources, actually those other things?
No.
Identity seems not to indicate anything in the entity, but rather in the observers. If they agree it's the same (use the same label), then it's the same.
It's not up to observers to decide, based on their interests, whether or not a portion of reality at one point in time and a portion of reality at another point in time have one and the same identity. The two portions of reality either do or they do not have the same identity, regardless of what anyone thinks and what anyone wishes. Observers merely decide what is it that they are talking about, i.e. what
aspect of reality they are describing, as well as what is it that they believe to be the state of that aspect of reality. In this case, the aspect of reality they are talking about is denoted by the term "the identity of a person". If a bunch of people agree that Skepdick is Biden, does that mean he's Biden? Of course not. If everyone agrees that Skepdick is Biden, does that mean he's Biden? Of course not. It has nothing to do with consensus.
The common mistake that materialists make is to think that, if all physical particles move, which means, if they never rest, if they never keep the same position from one moment to the next, that sameness is an illusion, a mental simplification of reality or something along these lines. That's false because, even though a physical particle moves, its movement can be restrained ( and it's probably inescapably so. ) If I lock you up in a dungeon for a period of time, and you constantly move inside of it, such that you never rest, such that you never occupy one and the same position two times in a row, you'd still be inside of that dungeon at every single point in time. That's sameness
despite constant movement. At every point in time, you're in that dungeon. Whether or not you're inside of it does not change
even though your position changes. Moreover, the fact that you
constantly move is an instance of constancy itself.
