I was thinking early, and I came up with a very strange idea that I've never heard of before(I'm sure there's a reason why), and I would like someone to help me figure out why it is wrong.
So, there's 2 approaches to what a human being really is. There's vitalism, that there's something special that a soul is composed of that can't be measured, which makes a person who they really are. This is sometimes an idea held by people of faith, with varying examples of what happens to that "vitalness" when a person dies; some suggest that it is recycled through reincarnation.
On the other hand, you have the purely empirical physicalist idea, that everything that exists is just matter. A person is the sum of the cells in their body. So I got this idea from a synthesis of physicalism, the principle of plenitude, and a simple education in physics(although these ideas seem a bit to axiomatic to be anything less than generalizations);
Matter is never created and never destroyed.
All matter that exists will always exist, but it can and will change forms.
Since matter is never destroyed and will exist forever, it will be arranged in every possible form imaginable(Or at least the forms that it has previously been arranged in) an infinite number of times.
Matter arranged itself in the pattern in the form that I am.
Since matter will exist and change forms eternally, it will eventually be formed into the exact same form that I am right now, again.
If a person is purely the sum of their matter, and the matter will create their form again, any given person will eventually be created again
I apologize for not being succinct, I'm trying to be as specific as possible
I certainly made a factual or logical mistake in there somewhere, and I'm trying to figure out where and if I can mend it or if I should throw the idea away.
P.S.:This is not about religion at all, rather it is about the possibility of a different form of something somewhat akin to reincarnation existing in the natural world. I simply added an explanation of vitalism to add a little background.
