It's possible. The Edgar Cayce readings, and other traditions as well, tell of the technologically advanced Atlantis and Lemuria of old. The Hopi believe there have been layers of civilizations over tens of thousands of years. It would be kind of arrogant on our part to assume we are the only civilization that has ever been on Earth. Fun and interesting to think about, isn't it?

I have seen on television that cities are being found every year under old cities. The holy lands they keep finding tunnels underneath the cities most know nothing about, these are mostly preserved although some have caved in. Then I saw in it was either Greece or Rome that they found old cities under newer cities, digging out these big cities that are like 50 feet down. The same for Egypt under ground they keep finding new places where there was once temples.

Earlyne Channy said she always felt there was a tunnel linking south America to Egypt, she felt this strongly and had always tried exploring the never ending tunnels beneath Egypt to find it, she never did. May she rest in peace my teacher from Astara.
