Stonehenge is not a sundial, nor an astronomical measuring device, nor a place of worship or sacrifice, nor a meeting ground. These explanations are mankind's attempt to explain Stonehenge, as the true explanation is too discomfiting. Stonehenge was built to the specifications of a reptilian King, who resided on Earth so long ago that humans were scarcely emerging. Yet the structure was to carry meaning for the emerging humans, which it has, to this day. Subliminal messages of power and sadistic treatment toward those sacrificed.
Humans look upon Stonehenge, and imagine the innocent struggling on the table under the knife.
They imagine a coven of evil surrounding them. They imagine no force on its way to rescue the victim. Stonehenge was built to fulfill the purpose it has, to insinuate itself into the subconscious of mankind, making it uneasy. There are those in the Universe who would terrorize mankind, and thus win conquest over their souls.
