The Bible noted that the earth is a sphere and sits on "nothing" more than 2800 years ago!
Isaiah 40:22
It is [God] who sits* above the sphere** of the earth
Job 26:7
He stretcheth out the north over the empty place, and hangeth the earth upon nothing.
How far has our sins been removed from us when we ask God to forgive us? Note the psalm below would make it finite if the circle of the earth were flat. If it is sperical with a pole, then east and west are directional with no end.
Psalm 103:12
As far as the east is from the west, so far has He removed our transgressions from us.
Matthew 24:40-44 speak of the gathering of the church that will take place in one single event. Notice that there are three differnet periods of time, evening, morning, afternoon. This is only possible with a sperical earth with inhabitants in every hemisphere.
The Hebrew record is the oldest, because Job is one of the oldest books in the Bible. Historians generally [wrongly] credit the Greeks with being the first to suggest a spherical earth. In the sixth century B.C., Pythagoras suggested a spherical earth.
Eratosthenes of Alexandria (circa 276 to 194 or 192 B.C.) calcuated the circumference of the earth "within 50 miles of the present estimate."
