They should have done a bit better demonstration and actually let us see the stuff on the guy. By keeping it under the clothes and the hat, it is very possible for it to only be regular armor of some sort. Such as a helmet or some very strong knee pads.

There are many geological structures in the world that appear to be manmade but turn out to be natural. Most of the time, they are igneous rock structures. These types of rock are composed of minerals that have specific angles of fracture. This causes the rock to also show these same angles of fracture. Basalt has this.

I remember watching a show on the History Channel about this underwater area. One person showed that the same structures appear on land but no one had ever tried to say that the land versions are manmand. No archealogical artifacts have been found in the area. Some people claim to have found places where carvings are done or holes have been drilled but these are not evidence that people constructed the entire structure. It is more likely that someone altered the rock at times when the ocean level was lower.

So far, all of the evidence points to this being a natural structure and not man made. Until a lot of artifacts show up to prove otherwise, science will continue considering this as an interesting place but not man made. There are a lot of people out there who will maintain that it is manmade. Mostly the diver operators in the area who take people there to look at it.

They did not try it with an actual china shop. If you watch the video again, they show a small clip of a bull in a china shop doing some damage. I think that they did not have near enough china and that their shelves were too far apart.

Here, at this ultra-exclusive petting zoo, we have substituted the rabbit food with 'Foldger's Crystals'. Let's see what happens.
