The central conceit of the famous “mythos” stories of H.P. Lovecraft was concerned with the idea that Earth had been colonized by malign aliens in the remote past, long before mankind arose and became civilized, who eventually became worshipped and feared as evil Gods by their human servitors. Eventually these aliens had been “banished” to another dimensional limbo by a benign Elder Race, but might one day return to reclaim the Earth “when the stars are right.”  
During his lifetime, Lovecraft encouraged other authors to write their own stories based on these precepts, and to develop his ideas. Countless authors accepted his invitation, including, inter alia, Robert Bloch, August Derlerth, Robert E. Howard, Henry Kuttner, Frank Belknap Long, and Clark Ashton Smith. The parade of other writers has continued, unabated, to the present day, and they include Richard A. Lupoff.

And yet civilization, in any form that we would recognize and acknowledge, has existed for a mere 10,000 to 15,000 years. We are thus asked to believe that Gug and her mate Ug led a primitive existence, hunting and gathering or perhaps scratching a few crude holes in the ground and dropping seeds into them each spring, and made little more progress than that for a minimum of 1,985,000 years. Following this there sprang into being virtually simultaneously the miracles of Angkor Wat, Babylon, Thebes, Kukulcan, Yucatan, and Cuzco...
