This new kind of animal God is going to "create" suckles its young.  "And God created great whales, (remember, whales are mammals) and every living creature that moves...which the waters brought forth abundantly, after their kind, and every winged fowl after his kind..."  Earth animals, water animals, and air animals.   How long did this take?

I'm reminded again of the verse in 2 Peter 3:8, "...do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day."   Peter wrote that.  And the Bible is the best commentator on itself.  All scripture should agree.  Even when written by dozens and dozens of different people.  There is no error in God's word.  Back in the Old Testament in Psalms 90:4--probably written by David: "For a thousand years in your sight are but as yesterday when it is past, and as a watch in the night."  In other words, a day is certainly not fixed at twenty-four hours as far as the Bible is concerned.  "Time has no meaning for God."

There were also some animals left over from the dark earth from Genesis 1:1-2 as well: Armadillos, Crocodiles, and other "plated" animals that lived in darkness and dampness.  Crickets, cockroaches, and similar exoskeleton types of creatures.  Anything that could survive in darkness and wetness were able to survive whatever happened after Gen. 1:1.  The Komodo dragon is an example.  Notice how similar some of these animals are to dinosaurs.  They probably are dinosaurs.  But the new types of animals aren't connected to them, and certainly didn't evolve from them.

Up to now, in the first chapter, nothing has been blessed by God.  But in Genesis 1:22, God speaks to His new creatures. He blesses the animals he has created out loud, and says, "Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth."  Or, in other words, "Have sexual relations for the purpose of reproduction."

That is not sex with male and male; not sex with female and female.  He created two distinct types of each species:  Male and Female.  Male and female whales, cats, hippos, camels, sheep...of every kind of animal.  All at once.  This sexual thing was blessed and made pleasurable for the purpose of reproduction.  Generation after generation has abused this gift and treated it with deviance.  We have become Sodom and Gomorrah.  Which God destroyed with fire.
