Another theory is that it was an observatory and it was used to mark the midsummer. Recently, they found that the people who visited Stonehenge at the midsummer, might have been visiting it at the winter solstice, when the sun sets between the largest arches. I believe it might be true because cultures had different religions and gods so the might be praying to their god or they are celebrating an event.
A different theory is that it was a place for the dead people as Mike Parker Pearson says. In Stonehenge they found buried bones so this is way the theory of being a place for dead exist. Lately they found a monument, not far away from it, just like Stonehenge but it was from wood and they believe it is the place for the living. A reason to argue that the two monuments are related is that the one is made of wood, wood might be the symbol of life because wood is just like humans, it grows and it dies and the reason the other monument is from stone is because stone might be the symbol of lifelong life. In my opinion this is the more possible way that Stonehenge was built.
