Adam was 933 years old when he died; that’s 933 years from the time he was cast out of the Garden, not from the time he was created.
He was created a ***spiritual*** ***immortal*** being. For all we know he could have existed billions of years as a spiritual immortal being, inside the Garden.
Time is not a physical phenomenon. Physicists do not recognize time as anything physical; it is a linear measure that transitions to a nonlinear measure in the presence of singularities such as Black Holes, but it is just a measure that is used in the definition of mechanical parameters such as velocity, acceleration, power etc.
Time grinds to a halt when a body approaches the speed of light.
God is infinite, God is light. Time has no attachment to God; He is infinite, without bound.
Marking his age from his expulsion and not his creation is an arbitrary assumption with no evidence in the text, unless I have missed something. The danger in positing such "gap" solutions is it makes the ordinary sense of the text so flexible as to be meaningless. One could sidestep the direct and obvious meaning of anything if one could always resort to redefining anchor concepts (like birth, age, death) at will. If the text provides a basis for an alternate meaning, well and good, the meaning is preserved. But without such a justification here, there is simply no reason to believe Moses was referring to anything but 933 years, start to finish, of Adam's physical being, as in the ordinary sense.
Time is not a physical phenomenon
That is open to interpretation. Special relativity implies a spacetime manifold in which time is merely the measure of location in a four dimensional grid, or as some call it, a tesseract. To the extent any of the grid's dimensions are physical, impliedly the entire grid is physical, including time. This is a useful way to see the experimental data on variable aging depending on frame of reference (e.g. time dilation, you leave earth at near light speed and return five years later in earth time but minutes later in your time, and the difference is real in a physical sense).
Bottom line, I've seen arguments for both a physical and a nonphysical view of time, and I remain bewildered. I lean toward the physical view because I do not see how time distortion based on gravitational distortion etc. can be excluded from the realm of physical being. But it is not a closed book to me.
