Interpretation

What the alignment can mean

The same overview discusses farmers and seasonal significance, while acknowledging limited clues about activity inside the stone circle. Ceremonial explanations therefore remain interpretations.

What remains unknown

What it cannot establish

A measured alignment alone cannot identify an extraterrestrial builder or explain every ritual. Claims of that kind need additional, independently checkable evidence.
