Huh? All the planets are shaped like discs. It's the earth which isn't a planet [wandering star].
What shape the earth is has no relevance to the shape of the things in the sky which are obviously not the earth.
And if they are, are they all facing us?
It sure appears as though they are.
The only object I can think of that looks like a circle when viewed from different angles is something shaped like a ball.
It depends on your vantage point and the relative distances involved. For instance, a concave shape can be perceived as a convex one depending on your vantage. In the case of very distant objects, as the lights in the sky are assumed to be; if the amount of distance we travel to change our vantage point is small in comparison to our initial distance to the object - then the visual deformation (making a circle seem like an oval, for instance) would be expected to be very small as well. For instance, during the course of the day, the sun changes distance from us as it rises and sets - yet it does not appear to us to be getting smaller or bigger as it does so. Of course it does get smaller and larger as the distance to us changes - but because the change in distance (or vantage) is so small compared to the distance of the object - we can't perceive this size change.
When you drop an object and it goes down, what is causing it to go down?
Its weight. Weight is an intrinsic and inexorable property of all matter. It "goes down" aka falls, because you lift it, because the matter you place it on cannot support its weight, and because the object weighs more than the media it displaces.
Objects of different weight fall at the same speed in a vacuum. Why?
They don't really, but the difference in speed is very small. Effectively so small that we teach this "rule of thumb" as "practically" correct.
The speed and acceleration profile of something falling is most influenced by the media through which it is falling and the buoyancy of the object. A balloon does not fall like a brick for this reason. When you remove as much of the air as you can and make a partial vacuum (full vacuum is not attainable) the brick and the balloon fall more similarly because the media you removed was most responsible for the differences in the way they fell.
If you could remove all the matter and achieve a perfect vacuum, then we would expect things to fall at the same rate. The why is the same as before, when the air was present - because the weight of the object is greater than the weight of the media they displace (which in the case of the perfect vacuum would literally be nothing/0)
The fact that things fall at the same rate, and instantaneously upon dropping them, is a bigger problem for the concept of gravitation than you likely realize. How would these imagined "fields" know to apply different amounts of force to overcome differing inertias and to accelerate equivalently? How could they do so instantaneously at infinite distance (or even a finite distance, for that matter)? It is much more natural, intuitive, realistic, and sound from the perspective of physics to recognize that the objects fall because they have nothing holding them up, and are heavier than the media they displace - rather than requiring magical and unequivocally unempirical fields that must violate multiple laws of physics in order to do what we observe.
I answered all your questions! Please let me know which one i missed.
what would be the reason to fool everyone into believing the earth is round
I'm sure you could imagine plenty of reasons if you wanted to - but it isn't necessary.
Humanity requires no help, no "fooling", to be consistently stupid and wrong as they historically always are; To believe ridiculous things are true and teach it to their children for centuries (if not millennia).
In my view, no one is "fooled" as much as they are "taught" through conditioning by rote under the guise of education, from childhood. Do you think we had to be "fooled" into thinking the earth was the center of the universe, or that spirits were causing illness (both things we taught at the best schools for centuries, or longer)?
what did anyone gain by doing this?
Again, there are many potential answers to this speculative question that you could imagine if you wanted to. But it isn't necessary, because it is based on a false premise.
I do not believe the earth is flat
Good! Belief is the enemy of knowledge, and to objective study of any kind (it's called bias).
If you believe the world is flat, spherical, or any other shape - you have faith not fact.
but there would have to be a reason to fool people.
Why? People fool themselves, and believe and teach all sorts of nonsense - and always have. Mythology is a natural/biological habit. It seems we prefer to make up an answer rather than live honestly with the self imposed (and unnecessary) shame of ignorance.
That said, speaking in terms of speculation/imagination - i'm sure you could imagine plenty of things which one or a group of people (that knew the world was not the shape and size we are all taught it is) could possibly gain from not sharing that or further - "fooling" people into not discovering it. For example, the aristocracy knew about and had maps of the "new world" for centuries prior to columbus... Do you know what happened when the cat was finally out of the bag and the poor slaves (often rebranded "citizens") found out there was a place to go to escape their miserable lot?
I see a wall of text but I don't see any answers to my question
You should try reading the "wall" of text ;) The answer is there, though you may not like it / find it satisfying. Tl;dr; The reason things fall down is their weight (and the interplay with the media they displace)
you have no idea what the motive is for pushing lies on people about a globe earth.
Lol. Seriously, read the text. It is easy to imagine what a motive to hide the shape of the world might be assuming you believed someone was doing that. As i don't believe anyone is doing that (and it doesn't seem like you do either), your comment is a nonsequitur.
Actually objects in a vacuum fall at the same speed. Why?
Actually, no they don't. Buoyancy (and drag) is still in play in a partial vacuum. They fall very similar (often too similar for the precision of our instruments to detect) speeds. You may want to re-read my previous answer to this question.
The acceleration profile in falling is most influenced by the media. The reason things fall is due to their weight, and although the weight of the larger object is greater - it has more matter to move!
Furthermore, the fact that it does appear that if a perfect vacuum were possible to exist - that all things would fall at the same speed essentially rules out the idea of a propagating "force"/"pulling" wave being the cause of it. It is not really a mystery why gravity waves are purely imaginary. If they existed they would need to routinely violate many fundamental laws of nature.
Because the weight of the object doesn't matter. Something else is pulling the object towards the earth.
Why do you think this? The weight of the object (and being greater than the media it displaces) is all that is required for things to fall. Scientifically speaking, it is the experimentally verified and verifiable cause of falling. It requires no magical "pulling force" which is utterly unempirical and hopelessly unscientific (which newton well knew and understood when he invoked it to solve an astronomical math problem).
