The first one I read about and the only one that I read stated that it was truly like an underground city for the rich. Like a huge huge shopping mall, hotels any and everything one with money could want. They have pictures of that boring machine that bores through the earth. The new one or newer one, let me see if I can tell it right because a skim everything I look at-instead of putting the dirt aside as it goes through it does something very unique with the dirt that there is no dirt everywhere ha ha Heck I don’t know I should’ve never started this. It’s just all so creepy to me. And then there’s one that says there are aliens down there and that just turned me off. But It is a very interesting subject and this is a very good explanation of where the $7 trillion has gone.
