How did a new satellites get in the right position?
Well there is no "right" position, but the answer to why they are where they are is over time.
The satellite must mysteriously set itself up so that it is neither pulled back by gravity nor let loose into space.
Utter nonsense. A satellite is where it happens to be due to very normal well understood models.
It must have that perfect balance between just enough gravity but not too much gravity.
Huh? That sounds like the kind of nonsense Biblical Christians spout. The amount of gravity is a function of the mass of the object.
How did the satellites get to that perfect spot in the first place?
Well, again, there is no perfect spot in the first place. That is simply silly. Just look at our own little solar system and you find satellites all over the place.
Oh yes, and stay in orbit for MILLIONS OF YEARS.
Billions even. They do it by falling.
Just curious but have you even had beginning introduction to science yet?
