That was an interesting read zid...I am going back to read some of your links...especially the chimp one.
I have been reading a bit about stone henge lately. It is quite fascinating. It would appear that it was used for a number of different things and changed to suit the beliefs and customs of each era.
From what I can gather...it started out at a burial/cremation site...then progressed and was added to. There also seems to have been the possiblility of ritual sacrifice there. And the connection to the river was a big part of the rituals.
Not only is what they did there fascinating, but what it was bult for. It would appear that they put a lot of thought and knowlegde into the placement of those stones. So much so, they could predict eclipses and other solar/lunar activity....It has my interest spicked, thats for sure.
Ha ha, I have more questions than I have time to answer them. I am constantly asking why, who, where, what, when. My partner just laughs at me and says, go on, get on google, you know you want to find out now. My joy of joys in life is asking why. I said to him, when I stop asking why, you will know I am dead.
