I think the above mechanical watch image is Ezekiel’s Wheel. Just putting this out there. Maybe have a chance to go over it later.
Another interesting ancient artifact, found in Nepal- has the perfect spiral, the space ship, the Grey alien and the Lizard, even the Spiders from Mars. The second is similar, it is silver-coated, see 2nd picture, and silver coating was not at all available in the time frame of this disk – 10,000 to 50,000 years ago.
