Stonehenge

So we've all heard of Stonehenge in Britain.
Well today I was bored and National Geographic was open to their new article about Stonehenge, quenching my natural thirst for ancient stuff like it, I started reading it.
Anyways scientist have now found early human migration (or something like that, they worded it a lot cooler) evidence around the area of Stonehenge. They've found about nine human sketal remains, one was from the Alps area of today, and the other the German/Swedish area, and for those of you that know this, but have never really thought about it...Stonehenge is in Britain and those sketal remains are 4,000 plus years old.
The article then went on to say they don't know, yet, what Stonehenge was built for, but some of the theories of why Stonehenge is there are...
1) Burial ground, they've found 250 plus remains and cremation evidence has been found along the banks of the nearby river, which at some time, flowed through Stonehenge.
2) Some big male god worship place
3) And one of the most interesting ones is... a healing ground/area whatever you wanna call it. Since most of the burial remains were there with a twisted leg, or torso injury, etc.
And sorry everyone, that my grammar is horrible in here (for those of you that care) but I'm wiped out. Just finished EOL's today, and 7 days till schools out!
