Does the Unobservable Universe not exist until the light from those distances finally reaches us?

Could this explain an infinite Universe with infinite amount of galaxies?

Someone living on a planet a trillion light years away doesn't exist to us, and we don't exist to them. So both appear to be living in a finite Universe.

Like draw distance in a computer game. The map can be infinitely large, but objects don't exist until you are within the rendering point.

We can't observe it, but it probably exists anyway. If it didn't, then the universe has a way of caring about us in particular, which is nice.

It's logical to say that the universe is infinite, assuming that spacetime is expanding at a constant rate in all directions. That is, spacetime is expanding at a rate of the speed of light. Assuming this is true, the universe must be observably infinite because t would be impossible to see beyond where the universe has expanded (you could not see beyond the edge of the universe because visible light would not exist there.)

You seem to be having difficulties understanding the magnitude of infinty. If you think about an infinite sequence, it's more than likely that another intelligent life form exists. In fact, it's almost completely impossible that it doesn't exist.

I'm saying the universe can be finite to an observer, while also being infinite.

And wait, spacetime is expanding at the rate of the hubble constant, 500 km/s/Mpc.
