You had to spoil the fun...didn't you Gackt! I wanted to believe so badly!
On the other hand...I'm seeing ancient technology...and it wouldn't surprise me one bit if Earth (and the Moon) has had underground bases with very high technology...for thousands of years. This would make sense if we are Prisoners of War on a Prison Planet with Grey Guards and a Reptilian Warden. No proof...but I'm leaning that way!
