You mistake his point. That’s easy to do since his actual point makes no sense. Since you can’t see it, let me “help” you by quoting it completely:
"Day 5 - Life From the Sea Through Birds
Genesis 1: 20-23 - And God said, “Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven.” And God created great whales and every living creature that moveth, which the waters brought forth abundantly after their kind, and every winged fowl after his kind; and God saw that it was good. And God blessed them, saying, “Be fruitful and multiply, and fill the waters in the seas, and let fowl multiply on the earth.” And the evening and the morning were the fifth day.
Keeping in mind God’s spirit was on the surface, and that the point of view is from the land as evidenced by the sun, moon, and stars being positioned on day 4, it becomes obvious that God’s declaration to, “Let the waters bring forth…” means He called life to come from the sea onto the land.
Vertebrates first made their debut on land during the Carboniferous Period (359.2 to 299 mya). By this period there were already forests of plant life on land, including large primitive trees, and the continents were already well across the equator.
Beyond the point of view already established, the real clue here is God’s call for birds in the same verses as life from the sea. The assumption has always been that these verses are specifically talking about sea life. Here God calls for ‘moving creatures that hath life’ and birds. We know birds didn’t remain in the sea, so why would we assume everything else did? Only now do we really know better. Birds, along with everything else, did actually originate in the sea.
We’re all but certain birds evolved directly from dinosaurs. In fact, all amniotic creatures are categorized this way; sauropsids, which are reptiles and birds, and synapsids, which are mammals and mammal-like reptiles. There is a direct line of evolution that can be seen from the first land vertebrates, to reptiles, to dinosaurs, to birds.
And the evening and the morning were the fifth day, or age. The age of life on land and birds in the air."

" When the events of ‘day 5’ are read in this context something really interesting can be seen in verse 21. In the above translation it says, “God created great whales and every living creature that moveth…”. In other translations, instead of stating God created ‘great whales’, it sometimes says ‘great sea animals’ (CEB), or ‘giant sea monsters’ (CEV).
The actual Hebrew words used here that are translated so many different ways are ‘e-thninm’, which means ‘the monsters’, and ‘e-gdlim’, which means ‘the great ones’. We now know that between the debut of vertebrates on land and the appearance of birds there were numerous creatures that much more aptly fit these descriptions than ‘great whales’ … namely dinosaurs.
Considering the intended audience at the time Genesis was written would have no knowledge of dinosaurs it’s unlikely they are what it was speaking of. It’s more likely that these descriptions refer to large reptiles or other large non-mammal creatures familiar to people in this age. However, if there were to be any mention of dinosaurs anywhere in the bible, it would be right here."

"## Day 6 - Living Creatures from the Land
Genesis 1: 24-25 - And God said, “Let the earth bring forth the living creature after his kind: cattle and creeping thing and beast of the earth after his kind”; and it was so. And God made the beast of the earth after his kind, and cattle after their kind, and every thing that creepeth upon the earth after his kind; and God saw that it was good.
Here that dividing line mentioned above between sauropsids and synapsids begins to take on a whole new context. In verse 24 God calls for the ‘earth’ to bring forth specific kinds of creatures. Knowing that life had already made its way onto land during ‘day 4’, there would be plenty of living material to use.
The first mammals appeared way back during the end of the Triassic Period (251 to 199.6 mya), most likely evolving from synapsid reptiles (see proto-mammals). All throughout the Jurassic Period (199.6 to 145.5 mya) mammals continued to etch out an existence in terrain dominated by dinosaurs, but grew no larger than a small rodent. But once the dinosaurs were out of the way by the end of the Cretaceous Period (145.5 to 65.5 mya) mammals really began to thrive as placental mammals, and then modern mammals, developed all throughout the Paleogene Period (65.5 to 23.03 mya)."
