Day five.  Here is where the fun begins.  The earth is ready.  The seas are ready,  The grass, flowers, and trees are ready.  The old dinosauric life is gone--with a some exceptions such as crocodiles, armadillos, crickets, numerous 'bugs'--just to name a few exceptions that made it through--and of course almost all of the sea life.

Genesis 1:20  "And God said, Let (let again) the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament (sky) of heaven."

When I looked at the dissection of birds--which sometimes swim, and fish--that sometimes fly, it is very noticeable that the fin of the fish and wing of the bird are very similar.  The tail as well.  Neither have lungs (with a few exceptions).  So if you are an Darwinist, and a Christian (which is an oxymoron to me),  this is one verse that might give you comfort.  But only on the subject of birds and fish.

  I personally believe the word  "let" was assumed.  "...Let  fowl fly above the earth in the open firmament of heaven."  Two different kinds of creatures.  Fish have gills.  Birds send oxygen directly through their bones.   One species survived the destruction in the water, the other in the air.  Birds would have made it through by nesting in floating debris.  And there was probably a lot of that.

The tide--the force that now drives the motion of the oceans is bringing creatures onto land.  Crabs, fish that prefer to lay eggs in sand and then go back to the sea.  Turtles as well.  Many creatures of the sea had no problem using both sea and land--thus providing a food source for the abundant life that is getting ready to appear in Genesis 1:21.

I absolutely love this book.  Up to here has been description, but now God is getting ready to speak out loud to his creation.
