No it was not built by Egyptians
Stonehenge is built in a way that the sun hits different stones at different times of the year. They had to know where to line up the stones. The stones are 'aligned' with the sun. At different times of the year, the sun shines on different stones, making it like a giant sundial.
The Druids (Celtic preists) built Stonehenge as a place of worship. I think also think they used it to map out the night sky, or a place to conduct sacrifes at but i'm not 100% sure on that
Probably not, but I don't think anyone has proved that it was.
