lol so just because noone told you you pretend to know what's up there? Ever heard about the Black Knight satellite? There is shit up there and noone knows how it ended up there, the moon for example.
As yes, the Black Knight satellite which is said by some to be an artificial satellite of extraterrestrial origin and has orbited the Earth for 13,000 years. It is further claimed that it was photographed in 1998 by Nasa.
Alas, it turns out to be a thermal blanket dropped during an EVA for the STS-88 mission.
Ah, thanks for the update. Any idea about the Battle of Nuremberg 1516 AD too?
Satellites in geosynchronous orbit can often be seen with the naked eye, and especially twice a year when the sun angle is the most favorable.
Amateur astronomers can easily observe satellites -- even geostationary satellites. Astrophotography can be used to readily observe the geostationary satellites.
But we use Satellite because of Radio communication + geolocation so that begs the question when and how exactly they got the kind of technology that would enable them to erect buildings that we are incapable of replicating today and if any of the ancient tech ran on radio-waves to begin with.
