One of these ornamental uses was to create the Nebra Sky Disk. The Nebra Sky Disk is a 30 cm or so copper disk painted a bluish green and inlaid with gold. The gold depicts a number of astronomical phenomena like the sun or full moon, crescent moon, and the Pleiades It has, after being accepted as authentic, been attributed to the Unetice Culture of Germany. There are two theories on what the disk is, one of which is credible and the other, slightly off kilter.
The more credible explanation is that it is some sort of star map that was used in some sort of religious setting. The slightly off explanation is that it is connected with the things around Europe like Stone Henge that represent an age when ancient man was visited by ancient space travelers. In this explanation the Disk could have been a map on how to meet up with the ancient aliens at a later date. If this is true and although I haven't yet seen Prometheus, I suggest that we not follow up on that map so as not to invite unwelcome trouble.
