To chase the idea of infinity, we must start at 0 and progress forever. All science and mathematics I'd imagine is based in line with that.

If you chase a finite result, you need a start figure to provide an answer.

Infinity assumes no end.

The finite must end.

Both the infinite and the finite exist in the minds of the living.

All life lives in the living.

We subjectly can only know the living.

The dead doesn't subjectively exist.

Life only can exist in you, the you right now reading this.

There is no other than you.

There is no you, without I.

Without the living nothing can ever exist, therefore existence is the only thing we can ever be sure is real.
