Asking for that is denying all the things working against you:

I agree with the above – you could however add another hundred or more issues that have been discussed as potential reasons for why the ancient megaliths question has not been resolved.
Those are issues working against everyone attempting to resolve the enigma – not just me. They are issues that have been on the table for thousands of years - for as long as the origins of anomalous sites have been contemplated.
One may as well attempt to prove the existence of God.
