What came first, respiration or ATP?

If respiration is used in order to produce ATP, but it needs ATP in order to function/get through glycolysis, how did respiration first happen in order to produce that ATP?
This is like asking what came first the hen or the egg?

When Luna Lovegood was asked a similar question, she said, "A circle has no beginning." So if that was good enough for Ravenclaw, it's good enough for me. :tongue:
