The Flood

The Lord said to Noah, "You and your entire household go into the ark, for you alone I have seen to be righteous before Me among this generation. Take with you seven each of every clean animal, the male and its female, and two each of every unclean animal, the male and its female, and seven each of birds of the air, the male and female, to keep offspring alive on the face of all the earth. In seven days I will cause it to rain on the earth for forty days and forty nights, and every living thing that I have made I will destroy from the face of the earth."
And Noah did according to all that the Lord commanded him.
Noah was six hundred years old when the floodwaters came upon the earth. And Noah went with his sons and his wife and his sons' wives into the ark because of the floodwaters. Everything that creeps on the land from clean and unclean animals and birds came in two by two, male and female, to Noah into the ark, as God had commanded Noah. After seven days, the waters of the flood were on the earth.
In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, the same day, all the fountains of the great deep burst open and the floodgates of the heavens were opened. The rain fell upon the earth for forty days and forty nights.
On the very same day Noah and the sons of Noah, Shem, Ham, and Japheth, and Noah's wife, and the three wives of his sons with them, entered the ark. (Genesis 7:1-13 MEV)

Quote from Sweeping gene survey reveals new facets of evolution

QUOTE
[PARIS] Who would have suspected that a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species emerge?
And who would have thought to trawl through five million of these gene snapshots -- called "DNA barcodes" -- collected from 100,000 animal species by hundreds of researchers around the world and deposited in the US government-run GenBank database?
That would be Mark Stoeckle from The Rockefeller University in New York and David Thaler at the University of Basel in Switzerland, who together published findings last week sure to jostle, if not overturn, more than one settled idea about how evolution unfolds.
It is textbook biology, for example, that species with large, far-flung populations -- think ants, rats, humans -- will become more genetically diverse over time.
But is that true?
"The answer is no," said Stoeckle, lead author of the study, published in the journal Human Evolution.
For the planet's 7.6 billion people, 500 million house sparrows, or 100,000 sandpipers, genetic diversity "is about the same," he told AFP.
The study's most startling result, perhaps, is that nine out of 10 species on Earth today, including humans, came into being 100,000 to 200,000 years ago.
"This conclusion is very surprising, and I fought against it as hard as I could," Thaler told AFP.
That reaction is understandable: How does one explain the fact that 90 per cent of animal life, genetically speaking, is roughly the same age?
Was there some catastrophic event 200,000 years ago that nearly wiped the slate clean?

A global flood that destroyed all living things on land must have left evidence. The question is, do we recognize this evidence? Can a secular scientist, who think that religions are myths, recognise them?

For we cannot do anything against the truth, but only for the truth. (2 Corinthians 13:8 ESV)
