ELI5: Why do most life forms have a similar face structure?

Most life forms seem to have a similar "face" structure. IE. eyes above mouth, etc. Why?

Evolutionary descent from an ancient (very ancient) common ancestor. Mouths probably developed first... jelly fish, starfish, anemones, etc. have openings into their digestive areas. Eyes developed from light sensing "spots". As evolution progressed, creatures with the most advantageous changes reproduced to pass on these traits. Over hundreds of millions of years the basic plan obtained its "bells and whistles" we see today. If we were to anthropomorphize nature and evolution, they don't like reinventing the wheel. That is, if it ain't broke don't fix it. And it seems the basic facial plan works just fine and is passed along.
