Let's do a little thought experiment and have a look into the very far(?) future.
Shall we?
It is obvious that at some point in time humanity will cease to exist. Latest, when the last star runs out of hydrogen, it's over, but I guess, it will be far sooner. So: At one moment, there will be the very last human being.
What do you think? When will it be? In a 1000, a million or in a billion years?
