Some photos would have been nice to have seen. Taking peice of the stone was suppose to bring you good luck and peace. We will never truely know what Stonehenge was used for. It is a cool place to visit.
I think Stonehenge is another portal or magnetic point for Aliens, like a homing beacon type device. I think that Alien's who visited Earth in ancient times had a huge role in the creation of Stonehenge and other giant structures that clearly are well beyond the building ability of mere humans.
Like Easter Island, the Pyramids at Giza, The Nasca Lines, Mayan Temples and many many more I can't think of right now. There is just so much we do not know about our history or the history of Earth, Earth was here long, long, before Humans, that's for sure.
