Well if there are hundred of satelites around the earth why cant we see them lol ? We're able to see starts from  milies away and we cant see satelites that are close to earth ? How comes that an satelite didnt fall in earth like get inside the doom of the earth where gravity will drag him towards the earth lol.

1) Because satellites does NOT emit light, and even if it does, it'd be a very small amount that we won't see here on earth since it won't even pass the atmosphere, while in other hand, stars emits dozen of light, energy and heat, just like our sun, so we can see it's light on clear skies, in fact, 80% of stars aren't visible from cities, because of the light emits from street lights and so on.

2) Simply because a satellite moves fast enough to orbit the earth, not so fast to escape the gravity nor so slow to fall in earth. 

I didn't go in details, you could watch dozen of youtube videos that explains it with better and understandable ways.
