THIS STONE WAS FOUND DEEP IN THE GROUND, where the sand deposits were a minimum of 100,000 years old. No big deal about that, but there is a three prong electrical device sticking out of it. This tells us that some intelligent being, 100,000 years ago, had a reason to put a three prong metallic electrical devise in to a rock. Of all things, why - - in a rock. Running electricity in to the rock, will heat the rock. Maybe they wanted warm rocks.
