Is there a distinction in metaphysics between “A exists” and “A is”?

Answer 1

To say something 'exists' is to give function to it, i.e. existence, "it is here"

To say something 'is' implies a purpose to that function.

Answer 2

The need for a distinction precludes this question. All efforts to make metaphysics a science have failed.
