I’m amazed at the ignorance of some people that type replies as quick as the thoughts come into their minds.
The Bible is clear about all aspects of the flood, the opening of the firmament, where the waters came from, where they went and the transformation of the land masses of the earth.
It would erase the confusion of flood rain 40 days oh how can it be ??? etc.
If the Uncle Joe types would do in depth studies into those aspects of the Bible that explain all these things instead of reaching back to secular and religious history to prove one belief system is superior to another their lives would be enriched immensely.
A small part of the water already existed in the clouds of heaven, and some remained there afterward. But the main part came from the pressurized fountains of the deep for forty days. That water overflowed the earth and is still with us as oceans, seas, glaciers, and water in transit in the known evaporation/precipitation cycle.
Despite the opinions of the global warmists, they forget that there is only so much water, and it can only decrease, not increase. There cannot be and will never be a flood like that in Noah's day. If the sea level increases a little bit for a while due to the melting of whatever ice we have, we humans will adjust to it, until the next ice age cycle comes.
Take a look at Genesis 7:11, 8:2; Proverbs 8:27-29; and Revelation 14:7 for confirmation ofd the thoughts here.
