what have we talked about in the course that would refute the “just a” part

Introduction

Proverbs 18:17 The one who states his case first seems right, until the other comes and examines him.

Does the Bible teach a flat earth?

Some people believe in the flat earth because they have been convinced that the Bible teaches it. So they believe that by denying the FE, people are denying God’s word. IF the Bible taught the earth is flat, their argument would be sound.

The case for a spherical 5 earth

We can use observation and reason to figure this out. It is so easy to see even ancient civilizations understood it. There are several evidences we think are impossible to refute:

The earth and the moon

Things disappearing over the horizon

People have often noted that ships coming up over the horizon appear sail-first. That is, the highest portion of the vessel comes into view while the lower parts are still hidden by the bulge of the earth. It’s so well known that there is an old naval term for it: ‘hull down’.

Sunrise and sunset

Furthermore, the sun rises every morning, and the sun sets every evening. We can clearly see the round disk appearing and disappearing piecemeal. Its apparent diameter stays almost the same, as does the moon’s, i.e. their angular size is almost constant (about ½°, or about half the width of your index finger held out at arm’s length).

Time zones

When most people think of a flat earth, they think of the sun going under the earth at night. This would mean the entire surface would be illuminated as long as the sun was up, and all parts of the earth would experience the same sunrise time and sunset time. However, we know that different longitudes have different time zones.
