I surmise Adam and Eve were created at what we consider approx. 33 years old.

Thus, maturity Isn't evident nor complete until the early 30's.

But Adam and Eve were then newborns in their 30s. I would think, under your scenario, maturity would come in a person's 50s or 60s.

"But Adam and Eve were then newborns in their 30s."

Nope.
Just created ... not new born.
