While trekking in 1998, John J. Williams discovered a strange metallic protrusion poking out of the ground. After uncovering an odd-looking rock, he cleaned it and carried it home. According to an analysis he had done, the rock is composed of quartz, feldspar, and granite. Electrical engineer William Williams estimated the age of the granite to be about 100,000 years.

This gadget was neither welded nor soldered; rather, it was an electrical component of the rock with a weak magnetic attraction. Williams stated he found it far from human civilization, but he never disclosed the exact location of this discovery. His hypothesis? This rock is an old alien technology.
