I agree that when people talk about ancient civilizations, they tend to make things up, often assuming religious symbolism where none may have existed. David Macaulay's Motel of the Mysteries is a fabulous satire of that tendency and everyone should read it. But I also think calling Stonehenge a motte and bailey fortification is missing the mark. That's an easy enough interpretation that, if the archaeology supported it, everyone would accept it and move on. There's something more to it, and maybe we just don't yet have enough data to say what it is.
