Why is Stonehenge an enigma

By: Antonio Arguelles

Why

This is an enigma because nobody knows when it appeared,how it appeared, why it appeared, or how it survived so long.

Because

The prediction is that it appeared from somewhere in 3,000 B.C to 2,000 B.C. My guess is that the rocks were raised by ropes, some people say aliens or druids placed them. The purpose in my opinion was a gift to the king but other predictions are that it was an ancient healing site, a place where magic was stronger. I don't know how they surcived but my guess is that the rocks go into the ground.
