Future archaeology

In around 3,000 B.C. a henge was built, consisting of a circular array of 14 standing stones, surrounded by a ditch about 30 metres in diameter and 5 metres broad, possibly also including a causeway across it where the burial chamber now stands. It is not known what the purpose of this structure was, though as with all henges possible theories include a seasonal calendar, a temple to the heavens, ancestor worship or some other religious practice of which we have no conception.Description of the Bryn Celli Ddu prehistoric burial site

Henge and chamber on the Highgate / Balsall Heath border

Is it possible that this arrangement of henge-like mounds and central chamber could be excavated 5000 years from now? What hypotheses would the future archaeologists postulate about its function?
