Contrary to the popular straw man argument against flat earth, it is impossible to sail off the edge. This is because God designed the earth with a rim to contain the water.
When He assigned to the sea its limit, So that the waters would not transgress His command, When He marked out the foundations of the earth, Proverbs 8:29 (NKJV)
These water-containing edges, which are also called the “ends” of the earth, consist of an ice wall that surrounds the circle of the earth. The continent of Antarctica does not exist, which is why it is so closely guarded today. The powers that be do not want us to find out that we live in an enclosed world created by God.
God told Job that the earth was formed like clay under a seal. We do not use these devices any longer, but the picture below shows how edges are formed when the seal is pressed into the soft medium. This is how the seas are contained on the “flat” earth.
God created it. He should know.
