The Nebra Sky Disc ~ "Pre-Flood" High Technology?

The Nebra Sky disc.
Found on top of Mittelberg mountain in Germany, amongst a horde of Bronze-age relics, mostly dating to around 16 hundred BC.  However, there is a possibility of this artefact actually being pre-flood… It is the oldest chart of the heavens in the world, but additionally, it displays an astonishing level of skill, creativity, astronomical knowledge, and indeed accuracy. For a considerable time, reams of quote, “specialists,” attempted to discredit the Nebra Sky dish as a fake, however, after numerous in-depth examinations of the artefact, it has reluctantly been academically accepted as authentic. It is a bronze disc about 32 centimetres in diameter with a diagram of the heavens embossed onto it in gold. It shows representations of the sun, moon, Pleiades and three other crescents, two presumed to be horizon lines and the other a possible Solar Barge. The difference between sunrise on the summer solstice and on the winter solstice is 82.7 degrees at this latitude, the actual difference between the sunsets on the two solstices. The two arcs are said to represent the portions of the horizon where the sun rises during the year. It has been variously proposed that the disc was intended as an astronomical tool, and that through comparison of the skies, and a visual display of the extremes of the rising and setting positions of the sun, with the disc in a horizontal plane, it could be used to determine the time of year.  In addition, it is proposed that it was used to calculate the difference between the solar and lunar cycles, in the form of adding a 13th lunar month, something which is required every two or three years. It is perhaps relevant that the cache site was found on the top of a hill, a good place for observing the suns movements. The site was surrounded by an artificial low bank, which could be used for measuring the position of the sun on the horizon. Could the Nebra sky disc be an extremely ancient relic, rediscovered by a people around 16 hundred BC?, Partially decoded, and used by these people as their own advanced tool for astronomical observations? A group of German scholars who studied this archaeological gem, released the following assumptive conclusion, quote. "The sensation lies in the fact that the Bronze Age people managed to harmonize the solar and lunar years. We never thought they would have managed that, the functioning of this clock was probably known to a very small group of people," end quote Also, According to german astronomer Wolfhard Schlosser, of the Rurh University in Bochum, based on the object, the Bronze Age sky gazers somehow already knew what the Babylonians would describe, well over a thousand years later, "Whether this was a local discovery, or whether the knowledge came from afar, is still not clear," Schlosser said. Is the Nebra Sky dish an advanced, pre-flood relic?  With specialists pertaining to such assumptions regarding our history, it is often forgivable to doubt these modern day attested explanations.  Regardless, the sky dish is clearly an amazing object, which thankfully, still exists within the public eye.
