Did I just disprove “nothing” happening after death and any idea of an afterlife while showering??

Hear me out:

Most people have an idea that when they die, either they will go to an afterlife in some sort of perpetuity—like heaven or hell—or that “nothing” will happen.

But nothing, by its own definition, does not exist! It’s a placeholder idea representing value as a concept; there no such thing as a “nothing” existing out there in space or anywhere in the universe.

So too is the idea of permanece, there is nothing in the universe that is permanent, not even the universe itself (as far as we can tell using science), so the idea of a permanent afterlife is just as implausible as a permanent non-afterlife… right?!

Therefore, most people’s ideas of what happens after death just can’t be possible, including the idea that “nothing” happens.
