The earth is a ball or sphere or anything but flat or possibly concave.

BoatsThe age old "ships go over the curve" has been disproved several times over since the invention of the telescope, but for the sake of this debate, I'll show you one video, and provide a simple explanation. I can understand why people long ago believed in a spherical earth. They saw boats appear to go over the horizon in all four directions. At a distance, the ship"s hull seems to disappear before the sails and those ancient geographers felt this would only happen if the ship was dipping behind the convex curvature of the spherical earth. This assumption is actually incorrect and if they would have timed or measured the distance that each boat had gone before dipping below the so-called curvature, they would have seen that the "ball" they thought they were on was far too small for their other calculations.The reason for this is simply the result of perspective. This exact thing will happen on earth whenever something is moving away from the observer. Take a vehicle for example, on a long and flat stretch of a highway. If you watched a car that was driving away from you, the car would appear to slowly get lower and the tires would morph into the road. Soon the body of the vehicle would appear to be scraping the road. So, one may assume that the car has gone over some sort of curvature, but again, this is not correct.One way to prove this is to bring out a pair of binoculars or even a telescope. When the object in question begins to morph or "sink" below the horizon, looking at it again with the aiding instrument will bring the item back into full view. Did the telescope manage to bend over the horizon to see the item in full again? Of course not. The binoculars were able to allow you to see further and therefore the item reappeared in full to your perspective.So, next time someone tells you that the ship going over the horizon is proof that we live on a globe" tell them about a little thing we here in reality must deal with called the Law of Perspective. The boat that they think has disappeared from sight can be seen again through a telescope and this was in no way caused by it going over a hump of curved water. Which as we know, is impossible anyway! The natural property of water is that it ALWAYS goes flat. ALWAYS. The railroad tracks going away from you don't get closer together, coming to a point, it only looks this way, it works on a vertical axis too. The telephone poles do not drop in height, they only seem to.https://youtu.be...PlanetsFirstly, Earth is a "plane" not a "planet," so the shape of these "planets" in the sky have no bearing on the shape of the Earth beneath our feet. Secondly, these "planets" have been known for thousands of years around the world as the "wandering stars" since they differ from the other fixed stars in their relative motions only. When looked at with an unprejudiced naked-eye or through a telescope, the fixed and wandering stars appear as luminous discs of light, NOT spherical terra firma. The pictures and videos shown by NASA of spherical terra firma planets are all clearly fake computer-generated images, and NOT photographs. https://youtu.be...https://youtu.be... Water droplets have nothing to do with trillions of gallons of water with earth (solids) combined. Anything more than a drop of water, it will no longer remain a ball.SpaceNo, we don't know how vast space is, this information comes from one source, NASA. We are taking someone's word for it, therefore this argument is invalid. As for falling off, take a plate, an object sitting on the stationary plate will stay on the plate, take a spinning tennis ball, well you get the point. Even one soaked with a liquid, once spun, the water will escape the ball. Comparing a ball to a sack, hmm. No. Centrifugal force causes objects in the sack to be forced outward, stopping at the barrier, in this case, the bottom of the sack. The tennis ball however is more like the earth. And you know what happens to objects on the ball, even with a barrier, things will not stick to the ball.https://en.m.wikipedia.org...
