Robot in Tehotihuacan new tunnel.
Hi Kandinsky, That reminds me of another question I had about this tunnel. The pit was covered and the tunnel was filled in to near the ceiling from what the images show. Has it been confirmed that this was done deliberately or could this be from mud/rain run off?
This story reminds me of the labyrinth of underground chambers found in Egypt not long ago. I think they are still digging these chambers out. This entire underground complex is also filled up to near the ceiling with dirt which is said to be very compact. My question here is the same, did the ancients fill these underground chambers in by hand or could this have been caused naturally by mud flows?
