1. Nobody has successfully debunked the Wyatt site perse yet, though there are debatable Wyatt specifics about things studied at the site which would likely be the case no matter who discovered it.
The Wyatt site makes a lot of claims, yet, provides no evidence for those claims.
For example, no one can view the "ark of covenent" , no one has been able to look at the 'wheel' that wsa from the parting of the red sea.
Frankly.. if the evidence for the claims can not be produced, the claims are false.
