neither would there first five children who were conceived and then born in a matter of minutes on the Sixth Day of Creation. The nine month gestation period which calls for the umbilical cord was a punishment for Eve's sin.
Now THIS is a new one!
Not really. G-d said "Harbah 'arbeh `itztzvonekh veheronekh" ("I will multiply [or lengthen] your pain and your conception"). Thus the human gestation period was lengthened, whereas Adam and Eve had five children on the day they were created.
Why do sinless ANIMALS have long gestation periods and umbilical cords?
I suppose the same reason sinless animals suffer and die. I don't understand it either. But I do know that Adam and Eve's sin affected the entire universe as well as themselves.
Where is THIS recorded?
