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.

Dropping a rock in a pond does create ripples moving outwards, but this is more like dropping the whole pond. At once. Perfectly flat.
There is no centre to the ripples because the whole pond arrived at once. So instead we get the little bits of wishy washy movement left over, but there’s structured order to it beyond “this was caused by dropping a giant sheet of water all at once”.
