And it came to pass after seven days, that the waters of the flood were upon the earth.

Augustine of Hippo
AD 430
It is now time to examine the evidence that proves convincingly that the biblical years, so far from being only onetenth 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 twentyseventh 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 thirtysix 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 twentyseventh day of the mo...
The fact, too, that he brought on the deluge for forty days and nights is a further wonderful sign of his loving kindness. His purpose in his great goodness was that at least some of them might come to their senses and escape that utter ruin, having before their eyes the annihilation of their peers and the destruction about to overwhelm them. I mean, the likelihood is that on the first day some proportion were drowned, an additional number on the second day, and likewise on the third day and so on. His reason for extending it for forty days was that he might remove from them any grounds for excuse. You see, had it been his wish and command, he could have submerged everything in one downpour. Instead, out of fidelity to his characteristic love he arranged for a stay of so many days.
And then what? “All the fountains of the great deep were broken up, and the flood gates of heaven were opened. And the rain fell upon the earth forty days and forty nights.” And a little later: “And all flesh was destroyed that moved upon the earth.” And again, “And Noah only remained alive and they that were with him in the ark.” Here and now I wish to ask them who call God indifferent to human affairs whether they believe that at that time he either cared for earthly affairs or intervened in them.
