the real problem with cable is the truthfully most of it is hellish...............this programme stood out like a beacon......................threw out the usual suspects (Von Daniken etc) but it was interesting in ta few ideas of how Monoliths and larger came to be.....................Dont worry aboput not having cablew you are saving a fortune and with the web and sites like this knowledge can be found.......

This is quite an interesting place to explore
