I mean if I drop a rock into a lake, its makes circles and the outermost circles are the oldest. Or if I blow something up, the furthest debris is the oldest.

The analogy doesn’t work though, because *space* expands from the big bang. Every point traces back to the same, and depending on your frame of reference, everything is moving away from you just as fast according to distance.
It would be like you are in the center of an explosion, but when you move a very far distance out into one side of the explosion, you look around and note you are *still* seemingly in the center, with everything exploding away from you just as evenly as your last viewpoint.
With no edge, and every far off point expanding away equally, there is no true “center”. Every point is just as “center” as every other point in space.
EDIT to continue: To leave the furthest edge of the explosion, or to travel beyond the furthest ripple in the ocean, is to step outside of space itself, which isn’t possible. Space was once contracted to a single point, but “where that point is” isn’t a question that makes sense, because ALL space of the universe was only there, and there was nothing beyond, because “beyond” implies… well, space.
