Why is there no “Center” of the universe if there was a big bang?

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.

Imagine that the entire universe and everything in it existed in a single point. Consider that, even though infinitely small in dimension, there is still the capability for space to exist within. We didn’t know for sure what space was like back then but for the sake of my explanation, assume that the entire universe was 1000 astronomical units from one end to another. In this hypothetical situation, if a big bang did occur, the length of each astronomical unit itself would literally begin to expand. Not like if all of humanity arbitrarily decided that a meter would now be considered to be the length of a mile, I mean that every bit of space would essentially extend in all directions, literally growing.

I like to think that the universe was and will always remain infinite in dimension. That, in a sense, the universe was always the same size, but rather than 1000 astronomical units, its infinite astronomical units. So considering that, if every point in an infinite space is growing, how could there be a center of infinity? There is none.
