Genesis 7:11 In the six hundredth year of Noah's life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened.
The water not only came from rain but from underground also.
Thanks, I knew that. I have read Genesis a couple of times. I wonder if it was salt or fresh water. A lot of underground water around here is brine.
