Au contraire.
Granite = quartz = piezo. The vibration on a partially isolated granite structure caused it to resonate. This as we well know causes stresses which excites the granite to produce high voltage. It's all there.
Of course tribal primitives just out of the stone age could not have conceived of this design let alone manufactured it so it had to be the work of visitors.
Loads of evidence. However if you prefer to avoid it that's your divine choice.
Over to the skeptics.
I've never heard a person rationalize so much just to make disconnected ideas fit into a personal fantasy as you. So far I've heard:
Lots of talk about large stones with smooth sides, pock marks and/or having a perfect geometric shape (which they don't).
Lots of talk of pyramids being used as generators, which is not only ludicrous but impractical as well.
Lots of talk about ancient and/or religious pictures depicting alien flying craft, which are actually religious symbolism.
And lots of talk about a carving supposedly showing a light bulb, which is in fact a symbolic picture of a plant (and BTW, if that is an alien's idea of a light bulb, then they must be the worst electrical designers in the universe).
And yet, no substantiation of aliens having been here in the past.
But of course I'm simply being "illogistical".
