All of this has been addressed over and over again. We know how far away the Sun is. We've known for hundreds of years basically how far away the Moon is and now we know within less than an inch how far away the Moon is.
Aristotle said that what is now known to us as Halley's Comet was some sort of a disturbance in Earth's atmosphere. He said that based on the same sort of simplistic thinking employed by Flat-Earthers. Aristotle at least had the excuse of having lived in the Pre-Roman Iron Age!
It was Tycho Brahe who, in 1577 (over 400 years ago) disproved Aristotle by using parallax measurements to prove that the comet had to be further away than the Moon. A lot further away.
It was Edmond Halley who, using his friend's freshly published law of gravity, determined that several appearances of comets in the past were actually the same object and successfully predicted it's return in 1758.
You, being COMPLETELY ignorant of the history of astronomy and utterly incapable of even comprehending concepts like the Law of Gravity and Parallax nor the first thing about how such concepts are used to understand the world in which we live, have no basis to even understand the stupendous nature of such a successful prediction, nevermind to sit in judgment over it based on "what we experience", especially since you don't even get the "what we experience" part right!
I distinctly remember seeing Halley's Comet when it came around back in 1986. I remember being rather disappointed because it was sort of a dud. You really couldn't see it very well without binoculars or a small telescope. This poor visibility has primarily to do with the fact that it's closest approach happened to be on the opposite side of the Sun from the Earth and so it was only visible for short periods of time either just after Sunset or just before Sunrise (depending on the date you were doing the observations on).
At any rate, I'd like for you to explain that, David. If Newton's Laws are a fraud and there is no gravity. If we aren't in orbit around the Sun, if the Moon is not in orbit around the Earth, if Jupiter and Saturn are not in well understood orbits around the Sun and have no gravitational effects on objects like Halley's Comet, how is it possible that I knew, as 17 year old kid, that Halley's Comet was coming for months and months and months in advance. How was it possible for my 11th grade astronomy teacher to have a Halley's Comet count down calendar posted in his classroom from the very first day of school in May of 1985?
If it's all a fraud and a hoax, designed by Satan, to trick us all into buying into an unbiblical view of God's creation, why oh why does it work? How could it possibly work? Why isn't the work that Edmond Halley did to make this prediction missing? How is it possible that it didn't get destroyed in some mysterious fire? Why is it still there for everyone to read and to fully understand and verify? Why wouldn't someone have shown up to say, "Oh! Wait guys! This Edmond Halley dude was wrong and here's why and this is how I know it." Where's the flat-Earther who has refuted Galileo, Copernicus, Brahe, Newton and Halley (just to name a few)?
Now, I've chosen one single astronomical object to make this argument. There are literally dozens I could have chosen. Meteor showers, the fact that Planets are called planets in the first place, the Moons of Jupiter, the Moons of Saturn, the Rings of Saturn, the phases of Venus, the phases of Mercury, the orbit of Mercury, asteroids, the Aurora Borealis, the discoveries of the outer planets (i.e. Neptune, Uranus & Pluto) as well as the dwarf planets (Ceres and others), etc, etc, etc. Basically, the last 400 to 500 years worth of astronomical history stands against this intellectual vomit that you're trying to get us to swallow. I'm here to tell you that I'm done with it. You want to throw 500 years worth of history into doubt, it's on you and I mean on you personally, to make the argument. I will not entertain one single more second of anything from anywhere other than type written arguments that you personally write and post. If it's a video, I'm ignoring it. If it is in quotation marks, I'm ignoring it. You will either make the argument in your own words or you can suck on your own intellectual vomit and I'll sit back and watch you choke on it. And I do mean actual arguments, David. Arguments where there is more than just naked, unsupported claims like you've made with this painfully idiotic nonsense about the speed of the Moon.

I've written down all claims the of those who believe the earth is flat.
I'm not the author and originator of any of it. Some arguments are good, some not so good.
I started studying cosmology 5 years ago as the last of my personal concerns after theology and evolution. I started with modern cosmology, because I took the heliocentric model for granted but I knew Einstein had combined space and time which is an irrational construct. So I wanted to know how and why we had come to this point. Experiments that were supposed to tell us exactly how fast the earth was moving though space instead proved the earth was not moving at all so relativity was made up to save the heliocentric day.
So, flat earth is back in a big way. Watch the video of Mark Sargent and you'll see just how big.
Space time relativity is where we are today, moving into multiverses, and these propositions are mindless/irrational science fiction.
Galileo, Copernicus, Brahe, Newton, Halley, Einstein, Hubble, NASA.....all have to be looked at to see if they were correct or not in my opinion.
For me, personally, it's not confirmed in my mind if flat earth or globe is correct. I have not ignored your input, I'm grateful for it. It's not easy to attempt to rebut a GE view that's been covered in mind boggling calculations. To much of GE has been founded by too few who we must trust their observation and more importantly how to interpret those observations. Take Hubble for example.
"Hubble had measured the distance to over 20 galaxies using spectral analysis on the distant objects. Hubble noticed that the spectral lines were red-shifted, meaning they were moving further away. In fact, Hubble noticed the farther the galaxy was, the greater the red-shift was, meaning that the farther away a galaxy was, the faster away it was moving."

I read the article and watched the video and wondered, "what did he actually see?" Did he just see that stars have color? Did he see stars changing color? How can anyone validate his conclusions apart from his own interpretation of what he says he is observing? We don't see anything changing from red to blue or vise versa here on earth so why should we believe it happens in space when viewing stars?
