Here is an interesting term I have been hearing lately... 'atmospheric river'... Our atmosphere can apparently contain huge amounts of water under certain conditions. Which brings me to this passage in scripture.
"In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened. And rain fell upon the earth forty days and forty nights." - Genesis 7:11-12 ESV
Before the great flood there was no rain. Mist formed to water the garden. What a different world it must have been. Our first ancestors lived hundreds of years at a time when the world was young. The atmosphere must have been like an ocean not just an occasional river.
But when Noah was 600 years old the bubble burst.
It is always amazing to me how scientific discovery keeps reinforcing the reliability of the scriptures.
