The previous poster was referring to how the swamp was made by man before Christopher Columbus sailed the ocean blue. There is a lot of evidence pointing to the Templars sailing to North America long before good ole Chris did.
The people that landed on Hawaii before Captain Cook, are said to be people from South America that “canoed” all the way there. How did the people get to Easter Island? Speaking of South America, a lot of information is being uncovered there as well that has changed what people believe about the Aztecs and Incas and others. Seriously and highly unlikely there is fraud going on with this show given the searcher history with Oak Island.
However they have never done the satellite scan to find metals beneath the soil. Why? This was highlighted in the WWII treasure hunt just recently but I have never heard the Oak Island crew use it. It would be helpful. This satellite tech has been used on the Skinwalker show and the WWII show and some others. This is not to be confused with LIDAR.
I’ve seen the TV shows & read about the claims regarding the Templars. So far to me all I see is circumstantial evidence & wishful thinking. Send links if you got more.
As far as Easter Island goes, Thor Heyerdahl’s work is highly speculative. The original inhabitants were Polynesian. They even brought the Pacific (Polynesian) Rat along. (It hitched a ride as rats do!) Origins of the rat are SE Asia as are the Polynesians. There may have been some South American influence, again highly speculative. If you know of more evidence please let me know.
Easy to fake things with a TV show.
If wet ground aerial (or satellite borne) ground penetrating radar won’t give you much.
I don’t know what the Skinwalker show is or what WWII show you are referring to.
I know LIDAR well.
