Yeah, I'd be careful putting too much stock in Ron Wyatt.
I think a lot of his claims have already been proven to be fraudulent.
That's doesn't mean the ark of the covenant isn't real, or isn't "somewhere"...
it just means Ron Wyatt isn't the guy with the answers.
Lots of people in Christendom have made bogus claims over the centuries.
Humans are a fallen race; they lie.
They lie for money, fame, power, laughs, acceptance, pain avoidance... a litany of different reasons.
It happens.
People make bogus claims.
It happens.
It will continue to happen.
We are actually commanded in scripture to check things out for ourselves, and verify if they're true or not.
Thessalonians 5:21
"Prove all things; hold fast that which is good."
We are to prove (test and verify) things, to see if they're true.
There are a lot of scriptures that support this position.
We are never supposed to just believe whatever we're told...
we're supposed to be cautious, and check people out.
