When I ponder the "births of the sons of Noah, Shem, Ham and Japheth", three in total, and those sons had 16 sons, and the increase continues at least double in the next generation, I cannot think that humanity has been very long upon the earth as the numbers would be astronomic. Even between the 1920's and now, about 100 years, there has been an increase in world population from 2 billion to over 8 billion.
It would seem that the world and everything living in it is not very old, thousands of years but not millions.
The deluge wiped off the face of the earth vast numbers of creatures living on the land and vast numbers of birds. When the flood started to recede as the wind dried it and the dry land appeared separated once more from the sea, vast numbers of creatures would have been deposited where the water receded at the border of what we now call continents. Is there any geological evidence of this?
I wonder if oil deposits which come from living creatures being crushed would be found near to coastlines, buried beneath a weight of water.
Wind blowing over cold water creates ice - did an ice age follow in some parts of the world?
Was there a huge deposit of sand, clay, lime which buried delicate structures like ferns so quickly and so fully, that the delicate shape was preserved before they could disintegrate, leaving fossils that are intact and complete? That sedimentary rocks could not have been laid down over thousands of years as the fern could not have survived to make a fossil?
In other words is there evidence in our world that there was a catastrophic flood in the history of the world which destroyed many animals including the majority of the dinosaurs, with so few left that they were the monsters or dragons killed by brave men, as told in Beowulf, or St George? Is this more likely and with greater evidence available than that a meteor strike was the cause of the death of the dinosaurs?
Another detail which struck me as I was reading, which is tucked in, almost as an aside, in the writing: "to Eber were born two sons: the name of one was Peleg for in his days the earth was divided". Did continental drift follow as a result of the flood recorded in the Bible?
The Bible is not a history book, or a geography book, or any other kind of worldly book - it is a book told by God through human agents who were given the words to write by the Holy Spirit - but there is evidence in it to ground it in real history and real geography.
We do well to pay attention to it.
