It is the only concept in physics. All else merely represent extensions of it.

The two most basic fundamental concepts are

1) Existence (the nature of existences)
2) Change (how their condition is altered)

All measurement boils down to these two considerations

Change is a function of existence. Before something can change or be changed it must first exist. This makes "existence" the most fundamental phenomenon and change (energy) secondary. I agree with Thomas' statement in that regard.
