Genesis, the book of beginnings, speaks of the moments where Adam examined and named the animals in God's new order. I'm certain that this process took place over a protracted period of time. I wonder where the porpoise fell into the line up?
Could Adam, in this state of innocence, converse with the porpoise? Or being the only being created in the Imago Dei, did thougthful, willful communication solely belong to the Godhead and the "living soouls" of Adam and later, Eve?
