Early man had only his own eyes, then Gallileo added the telescope and we could actually see objects going round other objects for the first time.
"In Venice on a holiday in 1609, Galileo Galilei heard rumors that a Dutch spectacle-maker had invented a device that made distant objects seem near at hand (at first called the spyglass and later renamed the telescope). A patent had been requested, but not yet granted, and the methods were being kept secret, since it was obviously of tremendous military value for Holland. ..."

yes, I meant that G added the spyglass to looking at the sky, not that he invented it. As far as I know he was the first to report doing so.
