>Pretty well accepted as tombs. They were originally covered with mounds and some still have them intact.
I do not believe that. To much effort and history proves people buried their dead under the floors of their own homes. A dolmen is a fantastic defensive structure while humans are sleeping, and a more day to day concern for humans is staying safe while sleeping. I can see Dolmens becoming tombs, when abandoned by the humans that may have perhaps used them as a defensive structure from wildlife and other humans, but again, not the primary factor for their construction.
Of additional interest is their locations, which are worldwide. Often no remains or artifacts are found in their location or vicinity.
>Pretty well accepted
nothing should be pretty well accepted considering humans are not the all knowing, truth-telling, species they seem to think they are considering their extremely short history of knowing anything. A pompous ass sitting in some ivory tower institution seems vested in keeping most things..... pretty well accepted. Were that the case we'd not have cellphone, or computers.

1. Did THESE people do that?
2. What about important people like kings?

Maybe for a few people. Not a whole village.
