I would not agree that it's the most plausible theory. It is a hypothesis but what this website is doing is selectively picking there observations to align with their already known conclusion. Because when you start digging into all of this stuff, even from these people, you start to get into very fringe theories beyond just a geopolymer limestone. They talk about melting granite and giant lenses and traveling the world and repeating this over and over. Some truly outlandish stuff. The more outlandish your claims are the bigger the proof needs to be. The only evidence they provide is that geopolymers are a possibility but that has been a well-known thing for many decades. They are lacking a lot of evidence to show this is really how the pyramids and other ancient structures were made.
