Why is giving birth so painful, for every animal? (Details )

Weather it’s eggs being laid, or live birth, it seems all creatures experience immense pain during the birthing process.

Obviously the pain is anatomical in nature. That’s not what I’m asking.

It seems like it doesn’t correspond with evolution. The pain could be viewed as a deterrent to have sex, and reproduce.

It feels good to have sex. Why is the outcome so painful for the mother?

Life has been on this planet for hundreds of millions of years. Why is the mother “punished” by mother nature?
