Well its somewhat interesting. For starters it isn't impossible that it's there. And if they were to have it, I believe this would be the way to treat it. I mean if you let someone in from a legitimate source like the History Channel or Smithonian, the story would blow up and recieve immense attention. That's just what you want to avoid, thousands of tourists flocking there, not to mention the possiblity of worse. It's not crazy to think that if it were there, someone would try to get there hands on it illegaly. The consequences of which could be catastrophic on a number of differant levels.
Now I was raised a Christian so I know the folklore, but I do not practice the beliefs I was taught, at least not all of them. And I most certainly don't believe in the boogey man to quote Dr. Jones. However it is our beliefs which make the possiblity so intriguing. Obviously were it to exist, it would not outright prove the existance of God, but certainly reinforce it. The sort of impact that would have on other religions and the world in general would be wild. There would be questions as to who the rightful keepers of the ark should be and weather or not it is safe or holds the ability to do supernatural things. Some would want to study it, which others would consider desecration. In my opinion the ark is best left to rest with it's rightful heirs.
All that being said, remember this. Were Indiana Jones fans, we have a bit of a differant outlook on the ark. Alot of us see the ark as a treasure beyond our wildest dreams. But at the same time we should respect the rules or power of the actual ark as set forth by the bible. Alot of people relate the Ark to "Top Men." thanks to shows like Family Guy, but it is not something to be taken lightly.
"All your life has been spent in pursuit of archeological relics. Inside the Ark are treasures beyond your wildest aspirations. You want to see it opened as well as I. Indiana, we are simply passing through history. This, this is history."
