The Bible itself clearly states that the Earth is flat. But Christians will deny this. I have debated many Christians on this topic and nearly Everytime they have came back with the same response. It's a quote from the Bible . . Isaiah 40:22
'' He sits enthroned above the circle of the earth, and its people are like grasshoppers. He stretches out the heavens like a canopy, and spreads them out like a tent to live in ''
The main word in the quote is circle but what they fail to realize is that a circle is a two dimensional object. It has Width and Height but it does not have Depth so by Definition a Circle has to be flat. The quote clearly states a circular Earth meaning it is a flat Earth. Unfortunately they do not realize this. A circle can be changed into a three dimensional object but it is no longer circle but now a sphere which the Earth is.
The common Rebuttal is '' They are the same thing because they are round'', No they are not, They are very different and people who wrote the Bible knew that. They had build Cities and Towns, Made Goverments and Civilizations and used and developed Agriculture as a way of life. I highly doubt that If you were to draw a circle on a wall and the placed a spherical object beside that drawing that they would not be able to tell the difference
