The narrator sure doesn’t make it any more credible. Gary’s finds could’ve come from anywhere. The Smiths Cove “structures” could’ve been someone building a....building. The island has a lot of porosity and natural openings and “tunnels”. It is, after all....an island. At least Marty actually came out and said he was just about ready to pack it in, until they found the “structures”. Riddle me this....WHY would someone bury Shakespeares works surrounded by WATER? WHO had the actual manpower to build such a concoction of nonsense, then have the manpower to go retrieve it and have so many scoundrels know about it? Oak Island is WAY in the channel....it would take an act of God just to FIND the proper island again! Looking at the big picture...there ain’t nuttin’ there but wasted money and one torn up island.
