The following is a completely naturalistic conclusion about what happens after death:

In the same way the birth of a brain caused a Self (you) - because there will be brains born (in the universe) after you've ceased to exist, and they will also cause Selfs - one of those new Selfs will come after the current Self (you).

[I did post here about this before, but I wanted to make a new post about it because this is a much more concise version]
