Genesis 7

It is now time to examine the evidence that proves convincingly that the biblical years, so far from being only one-tenth as long as ours, were precisely as long as the present solar years. This is true of the years used in giving those extremely long life spans. It is said, for example, that the flood occurred in the six hundredth year of Noah's life. But notice the full text: "The waters of the flood overflowed the earth in the six hundredth year of the life of Noah, in the second month, in the twenty-seventh day of the month." Now those words are inexplicable if a year was so short that it took ten of them to make one of ours. That would mean that a year had only thirty-six days. For so short a year (if it was actually called a year in ancient usage) either had no months at all, or if it had twelve months, then each month could have had but three days. How, then, [can we] explain the words of the text, "in the six hundredth year … in the second month, in the twenty-seventh day of the month," unless the months then were the same as they are now? There is no other way of explaining how the flood could be said to have had a beginning on the twenty-seventh day of the second month.

Then, a little further on in the same book [Genesis], one could just as easily have noticed the verse "Everything on the dry land in whose nostrils was the breath of life died." This means that everything that lived on the earth perished in the flood. Thus we find that Holy Scripture is accustomed to use both phrases—"living soul" and "the breath of life"—in regard even to beasts, and in the verse "All things wherein there is the breath of life" the Greek text does not use the word pneuma but pnoē.
