Creation Began; The Beings in Creation Did Not

Assumption:

Creation has a beginning, and it may have an end. The Beings in Creation, however, have no beginning and will have no end. They did not begin with Creation, nor will they end with Creation. 

Because Creation has a beginning does not imply that Creation is the only or ultimate beginning. The Beings in Creation pre-existed Creation; therefore, "before" Creation is conceivable.
