Gen 1: 6-7 And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so.
Gen 2: 5-6 For the Lord God had not caused it to rain on the earth, and there was no man to till the ground; but a mist went up from the earth and watered the whole face of the earth."There are some Christian Scholars who believe the whole earth was surrounded by a large cloud or blanket of vapor, like a green house before the flood. If this was the case the the whole earth would have been more warm and moist. Maybe these warm moist conditions would explain why animals and plants grew larger and why people lived longer.
Gen 7:11 "on that day all the fountains of the great deep were broken up, and the windows of heaven were opened."Some Christian Scholars believe that earthquake's and volcanic upheavals would have occurred in order to break up the fountains of the great deep. Some scholars also believe that the earth being covered with water plus volcanic ash in the air may cooled the earth and brought on the Ice Age after the flood.
Some Christian Scholars also believe that the earth did not experience seasons before the flood because of the green house effect. So the polar ice caps would have began to freeze for the first time. This pluss the excess water also may have caused an ice age.
Gen. 10: 25 And unto Eber were born two sons: the name of one was Peleg; for in his days was the earth divided; and his brother’s name was Joktan.During the ice age time the waters in the oceans would have been lower because of the volume of water that was frozen in the polar ice caps. With lower oceans it is believed that continents would be connected by land bridges thus making it one land. When the Polar ice caps melted the oceans would have filled up and the land would become divided.
