Or that crying is a mechanism that any normal mother cannot ignore? Human infants are born helpless, depending upon their mothers for their every need. Mothers get to know what a crying baby needs. There are different cries that a mother learns so that she understands the communication before verbal speech is learned.
Yes the Rainbow Covenant is interesting....in Gen 9:8-11 it goes on to say.....
"Then God said to Noah and to his sons with him: 9 “I am now establishing my covenant with you and with your offspring after you, 10 and with every living creature that is with you, the birds, the animals, and all the living creatures of the earth with you, all those that came out of the ark—every living creature of the earth. 11 Yes, I establish my covenant with you: Never again will all flesh be destroyed by the waters of a flood, and never again will a flood bring the earth to ruin."
So God was never again going to curse the ground or to flood the earth again, but that didn't mean that another judgment wasn't coming. The final judgment involves "the destruction of ungodly people", not damage to the earth itself.
2 Peter 3:5-7:
"For they deliberately ignore this fact, that long ago there were heavens and an earth standing firmly out of water and in the midst of water by the word of God; 6 and that by those means the world of that time suffered destruction when it was flooded with water. 7 But by the same word the heavens and the earth that now exist are reserved for fire and are being kept until the day of judgment and of destruction of the ungodly people."
I don't think it is a case of evil inclinations, as much as it is the physical, mental and spiritual imperfection that resulted from the disobedience of our first parents. (Romans 5:12) "Sin" is an archery term that means to "miss the mark".....we certainly do 'miss the mark' when it comes to aging, sickness and death....we also miss the mark when it comes to making good decisions, often with disastrous consequences.
None of this was ever supposed to happen.
