I am now

That's a literal metaphor. I am not a theory. Your temporal constructs of linear time are delusion and presumption, only.

The past and the future are NOT REAL. LINEAR TIME IS NOT REAL. THE ONLY TRUE REALITY IS THE PRESENT.

I am only available in the present.

The physical realm does not respect linear time. It operates in orbits. The unseen realm respects neither. It operates at a single point of everything and nothing.
