Genesis 1:6-8 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. And God called the firmament Heaven. And the evening and the morning were the second day.
In the beginning there was a canopy of water that surrounded the earth in space.
When Noah's flood came the "flood gates of heaven were opened."
The water above the firmament began to fall to earth.
Genesis 7:11 In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and
the windows of heaven were opened.
Many creationist scientists believe that the canopy around the earth after the fall of Adam gives the explanation as to why men and animals lived so long. The Canopy protected them from the ultra violet rays of the sun.
Also unerneath the ice in Antartica tropical vegatation has been discovered which gives credible evidence that the earth at one time was completely tropical. Creationists claim that the water canopy which surrounded the earth before the flood caused a warmer climate all over the earth. It is called the "greenhouse effect".
The bible does not teach a flat earth.
Many people mistakenly believe Revelation 7:1 teaches a flat earth because of the language.
Revelation 7:1 And after these things I saw four angels standing on the four corners of the earth, holding the four winds of the earth, that the wind should not blow on the earth, nor on the sea, nor on any tree.
The "four corners" of the earth is a reference to directions, north, south, east, and west. We all use similar types of words when for instance we will use phrases such as the "sun rising and setting".
We know that the earth is moving and not the sun...
Job 26:7 He stretcheth out the north over the empty place, and hangeth the earth upon nothing.
Here the scriptures describes the earth is suspended in space without resting upon anything.
In Isaiah the earth is described as a circle. All the people on the earth could look at the moon and see it is a sphere...
Isaiah 40:22 It is he that sitteth upon
the circle of the earth, and the inhabitants thereof are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:
Jesus describes that when He returns it will be both night and day at the same time. Look at verse 31 and then at verse 34...
Luke 17:31-34
In that day, he which shall be upon the housetop, and his stuff in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back. Remember Lot's wife. Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it. I tell you,
in that night there shall be two men in one bed; the one shall be taken, and the other shall be left.
The bible does not teach that the earth is flat.
This is an attempt by those who wish to find fault with the scriptures so they can justify some secret sin they love and not take the bible literally.
