Why don't you just ask people that have circumnavigated the globe with boats??? How on earth are you going to explain to them that they will never end up where they started, because if they couldn't go AROUND the world, then they'd have to change course, to miss the edge, and therefore would be going up & down the sides of the earth.
Also OP, why do you give bad karma to anyone that tries to call you out on this?? If you don't want negative or constructive feedback, then don't post things that are going to stir up a lot of controversy..
This is akin to the Spanish inquisition, whereas anything that the Governing body, or the church doesn't agree with, is punishable by death.
Here's a good way to see it.......

How can one prove that the world is round?
Asked by: Brenden Brewer
Now that we have access to space, the easiest way to prove the Earth is spherical is to leave it and view it from a distance. Astronauts and space probes have done just that. Every picture of Earth ever taken shows only a circular shape, and the only geometric solid which looks like a circle from any direction is a sphere.
One of the oldest proofs of the Earth's shape, however, can be seen from the ground and occurs during every lunar eclipse. The geometry of a lunar eclipse has been known since ancient Greece. When a full Moon occurs in the plane of Earth's orbit, the Moon slowly moves through Earth's shadow. Every time that shadow is seen, its edge is round. Once again, the only solid that always projects a round shadow is a sphere.
