Even if you accepted that a day as laid out in Genesis is 1 billion years, all it would prove is that the Genesis account once again is inconsistant with the evidence.
20: 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.
21: 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.
22: And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth.
23: And the evening and the morning were the fifth day.
So the sea critters and fowl show up in day 5.
24: 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.
25: 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.
26: And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
27: So God created man in his own image, in the image of God created he him; male and female created he them.
28: And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
29: And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for meat.
30: And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat: and it was so.
31: And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
And man and the land critters show up on day 6.
But your own link shows that life showed up about 3.6 Billion years ago or around midnight on day one, not on day 5 as Genesis says and we aren't even into day six which is when Genesis says humans will be created.
