Flat-Earth "theory" is redundant

"I've recently visited Russia and was surprised as to how many Flat-Earthers there are. So I have decided to see some of the arguments that people have to prove to me that the Earth is flat.""https://www.google.com...This chart has been tampered with, last I looked, there were 3 spikes all about the same level. More and more people are waking up, it's just using your God given senses, figuring out that you're being lied to, and examine evidence correctly. You are starting down a rabbit hole halfway through, once you realize what is really going on, the flat earth is an argument that can change your life forever, If you are open minded enough to entertain the idea (ie. go outside and imagine the earth as a stationary, infinite realm), to break the programming and indoctrination that we have all been succumb to for so long. If you are still in contact with any of those flat earthers, keep them. You have met some critical thinkers. Most of them are empirical observations, or common sense logic. I'm very impressed with your ability to Google proof the earth is not flat, and parrot their "excuse" for everything, I was there too, what reason do you have personally for believing you are on a ball?https://youtu.be..."First of all, Eratosthenes proved that the surface of the Earth is curved more than 2000 years ago"Eratosthenes makes an assumption and uses a false constant in this experiment. Firstly, he assumed the sun was 93 Brazilian miles away, and because of this, the sun's rays were all hitting the earth in parallel lines. However, in the flat earth model, the sun is closer, and small, and the sun's rays do not hit the earth at parallel lines, as seen on any cloudy day. Modern scientism claims it is due to perspective, like railroad tracks that are parallel to each other, but there is an obvious difference, these are lines that are seen at their proper angles, they are not parallel lines receding away from the observer.https://www.flickr.com...http://www.eratosthenes.eu... Evidence should be examined with scrutiny. There are two types of evidence, subjective and objective. Below is an explanation with examples of each type.SUBJECTIVE EVIDENCE is evidence that you cannot evaluate -- you have to simply accept what the person says or reject it.For example, Fred says "My foot hurts a lot." Is he lying? How much is "a lot"? What is Fred's idea of "pain"? ... a sharp, stabbing pain, or just his foot "fell asleep"?Harry says "That was a hard test!" Compared to what? Did he study? Is this just a subject he finds particularly difficult?Bill says "Boy, that was a great football game!" Compared to what? Who was playing? ... his son, the team he coaches, him, two pro teams?OBJECTIVE EVIDENCE is evidence you can examine and evaluate for yourself.If Fred walks in with a cane, and a knife stuck in his foot, you can make a decision without hearing Fred's opinion!If you read the test Harry talked about, you can decide for yourself whether it's hard.If you see a video of the football game, you might see great plays, high scores, a last-minute win, etc.Subjective evidence can be useful in a dichotomy, especially when there are several subjective points. However subjective evidence should be secondary to objective evidence. We will find that the majority of the ball earth theory is based on subjective material, while just the opposite holds true for flat earth evidence. When the evidence for spherical earth is not subjective, that evidence is often inconclusive, completely unrelated or simply misunderstood phenomena. What my opponent offers is objective, yet in this case, the proof works with both models, with objective evidence that is more likely evidence that the earth is flat.Contention one: No Curvature Joshua Nowicki has been photographing the Chicago skyline for a few years now.https://youtu.be... This would be impossible if he were doing so on a ball that is 25,000 miles in circumference. Modern science tells us that this is a mirage, but again, anyone who's actually seen a mirage, superior or otherwise, will agree that mirages are just "reflections" most of the time they are greatly distorted, and always upside down. Granted, visibility factors such as atmospheric blocking and waves and swells on lake Michigan sometimes do not grant this sight always, but the skyline is seen on a regular basis. This isn't the only instance of people being able to see further than they should, in fact, people are recently testing the globe, and the flatness of water to see landmarks that should be well over the curvature of the earth, and every time this test is done, no curvature can be found. This can be done easily if there is a fairly large body of water near you. All you need is a decent camera and the earth curvature calculator. This is yet another (objective) empirical proof that the earth is flat. I could present dozens of examples, but I feel that anyone can use Google, this is knowledge best obtained by actually researching, making personal judgements.https://dizzib.github.io... Contention two: GyroscopesDefinition from Wikipedia: "A gyroscope, not to be confused with gyrocompass, is a spinning wheel mounted on a gimbal so that the wheel's axis is free to orient itself in any way. When it is spun up to speed with its axis pointing in some direction, due to the law of conservation of angular momentum, such a wheel will normally maintain its original orientation to a fixed point in outer space (not to a fixed point on Earth). Since our planet rotates, it appears to a stationary observer on Earth that a gyroscope's axis is completing a full rotation once every 24 hours."https://youtu.be... Anyone who has ever owned a gyroscope can verify that they do verify that they do very curious things, even seemingly defying "gravity" sometimes. This experiment shows both, that the earth is NOT rotating, and can't be a ball. Gyroscopes have been spun up for hours at a time, and not even the slightest of rotations can be observed. https://youtu.be...Attitude indicators operate by use of a basic gyroscope. If the plane was flying over a ball, spinning, wobbling, going around the sun, which is bolting around our galaxy, that is rocketing around the universe at a combined rate of about 1,000 miles per second, they would be virtually useless, especially on transcontinental flights. Some higher end smart phones are equipped with a built in gyroscope. If yours has one, download any decent pitch indicator, and leave it on your night stand when you go to bed. Wake up in the morning and see for yourself that the phone has not moved or changed it's angle the entire time. Since your average person can get a good gyro and produce these same results, this is another (objective) empirically experimental proof that the earth is flat.Contention 3: The Compass Problem How a compass works on a sphere is problematic. For example, someone using a compass in South America should have a difficult time finding north. Why? Because the magnetic north pole would nearly be straight under foot, ie., directly towards the ground. A compass needle aligns itself and points toward the top of Earth"s magnetic field, which is now supposedly over far northern Russia. However, there is no indication that compasses have any more difficulty finding north in Southern Chile, South Africa, or Australia, or ever align themselves towards the center of the Earth.
