I should clarify, I'm not a fan of theories without much information based around them, and I didn't know if you knew this information. Thus I tried to debunk the general idea you had, because while it could be true, the reasoning behind it, is not the best.
That being said, a better counter argument to your theory would be:
The 3 units we know, were found in Mnt Minikami in Japan. And where Guyver 0 appeared to be, was in Arizona, because the relic he damaged is the same one at the bottom of the Arizona base where Agito got his control spheres to make his Gigantic. Even if you factor in continental drift over the next few million years, they would be completely opposite sides of the world..
