Planets are bodies which orbit a star. if you don't believe earth is doing that then you're right, it isn't a planet in your model. But then none of the other planets are really planets either unless in your model they do orbit the sun. If they do then I'd be interested to see the FE model of their orbits which match observations. If they don't orbit the sun in your model then I guess there are no such thing as planets at all. I wonder what you think they are.
All the planets are different, the inner ones are rocky, some of the outer ones are gas giants.
But other planets do have atmospheres and weather systems. They have night and day and seasons. They have volcanoes or evidence of past volcanic activity. They have mountains - Mars has Mons Olympus, the biggest mountain in the solar system. There is good evidence that liquid water did once flow on Mars and that ice may still be under the surface.
The conditions on other planets are not right for complex life but there is a lot of similarity. We might like to think of ourselves as special but, astronomically speaking, we really aren't.
The model of the earth as a globe coming about through observations is not a belief, it is a fact. There's the stick experiment of course, observations of the way the stars move and the way different stars are seen at different latitudes. The way ships disappeared over the horizon. These observations are consistent with the earth being a globe.
The fact of the earth being a globe was worked out thousands of years ago. The "ancients" had lots of other scientific ideas which didn't stand the test of time, subsequent ideas and observation superseded them. We no longer believe everything is made from earth, water, air and fire for example. But we do still believe that the earth is a globe because that model has consistently been shown to be correct. Over time slight adjustments have been made - we now know it is not a perfect sphere but bulges at the equator but at no point have serious scientists felt they needed to scrap the entire model and go to a flat earth model.
How do you think the discovery came about? You can't just say "If that's what you want to believe". If you disagree then what is your alternative.
And why do you think the spherical model obtained a monopoly? This is not like VHS vs BetaMax (not sure if that works in the US, in the UK they were two competing formats of video player back in the day). Both those systems worked, I've heard that BetaMax was actually technically superior but for whatever reason VHS was the one which became the standard. But when it comes to Round Earth vs Flat Earth, the Round Earth model works while the Flat Earth one doesn't.
Hence my point about GPS. There may be some glitches but, basically, it works. I was at work the other day, looked on my phone and I was where it thought I was. I went home and it got that location right too. I used it today when I needed to find something in an unfamiliar part of London. It's called the GLOBal Positioning System. There is a clue in the name. It uses 30 satellites to work out where you are. Satellite TV, as the name suggests, also uses satellites. These all have to be in geo-stationary orbit for this to work. If they're not orbiting a globe then what are they doing? How do they stay up? These things must work somehow. The airline industry plots routes using great circles round the globe as does the cruise line industry. These industries reliably get people from place to place. THEY clearly know where places are in relationship to each other and you lot can't even agree a map which works?
I must have missed the public campaign for a live feed from the ISS, I don't remember a clamour for one.
If you think you can explain a sunset on a flat earth with perspective then you're going to have to draw me a diagram of how that works. For photos like this to occur:
The sun has to be PHYSICALLY below the level of the clouds or the light has to bend so it looks like it is. I did an experiment to prove that and posted the proof in this thread
https://forum.tfes.org/index.php?topic=6875.160It is telling that no flat earther responded.
I can't even begin to imagine the complexity of trying to get a balloon which is the same shape as the supposed ISS to move in such a way to be visible in the exact locations and times their website says it will be and travelling at that speed. You think they can do all that but they can't get stuff into space?
As I said to Tom in another thread, all you lot have to do is take some observations of the sun or moon. If it is as close to the earth as you suppose then you can take observations from a few locations which you can agree the distances between. Do some triangulation and you can work out how far the sun or moon is. You asked in another thread why us round earthers don't just go to Antarctica to prove you lot wrong. As I pointed out in response, while a lot of people have now been to the South Pole it is still not something one can just do. The sort of triangulation I'm suggesting though should be within the skill set of some members of the flat earth society.
As I have come to expect from Tom when I ask a question he can't answer, he never responded.
