who can really tell me something about the lost city of the Incas?

Well, I don't know that much, but i know that the lost city is called Machu Picchu, and it was an indian city, a place that the Mexicans were trying to find. They never discovered it, so they decided to drop the search. Some people say that Indians hid their gold there from the white men.

the Incas were a lost civilization that was found in south American. because of there religion they used telescopes to tell about stars.

I think the lost city you are referring to is what is called "El Dorado". It's where a lot of gold was supposed to have been, and was supposedly seen at least once by a non-Incan, but then never found by any non-Incan again. Run a search for "El Dorado". I think the Disney movie (cartoon) was based on it, but I never saw it.
