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.

Despite the name, the Big Bang wasn’t an explosion: it was the start of a cooling-off process. It began at a point, but that point wasn’t the center of the universe: at that moment, the point was the *whole* universe. Space has been expanding ever since, but every point in the universe now was a part of that point back then, and still bears some of the residual energy from having *been* at that point. That’s why we can’t find a center: as far back as we can look, every point looks basically the same.
