So I'm thinking that little pinecone thing maybe represents the Pineal Gland! The Ancient Aliens premise says the Gods endowed man with intelligence, right? Well, the Pineal Gland according to Indian legend represents the inner eye. And many depictions in ancient art shows an eye symbol on the forehead. There is also the eye of Horus in Egyptian lore. Even today, eye symbolism is present in secret societies like the free masons and is even on the dollar bill.
