12 year old, astounding statement about aliens

While at work today at a local swim school, my wife was engaged in conversation with a very intelligent 12 year old boy, who is an aspiring priest.  The subject of ancient history was touched upon and she asked him his opinion of ancient alien theory.

His answer was simply amazing...

"there is no way that the mayans and egyptians could have built what they did without help from someone not of this earth."
