Is “EVERYTHING” centered around the cross?

Expressing this idea is difficult to relate. And I don’t understand the true significance of it. It seems that if Jesus destroyed his temple and which was “put back together” in three days. And to borrow a science quote from astronomer Carl Sagan: > If you wish to make an apple pie from scratch, you must first invent the universe. Did God/Jesus create/recreate the universe through the crucifixion and resurrection? Just thinking about it seems way to deep and over my head.
