Why do people turn into skeletons?

Answer 1

That's not exactly what happens, and that's not the end of it, either. We already have the skeletons inside. Skeletons are of course our bones. When all the softer tissue goes the way of all flesh, all that's left are the bones. But that only seems to be the final outcome, because the hard bones last so long. In fact, all the bones that have ever been and that will ever be will completely disintegrate after enough time has passed, even under the most ideal conditions.
