The GENERAL CONTEXT of such use is:
The term refers to those prior civilizations of humanity, prior to 9654 B.C. (before the occurrence of the geophysical Gothenberg Double Event), which did exist going back into the dim history of the aeons of human existence upon this world and, before mankind's "colonization" of the Earth (about 3.4 Billion years ago), elsewhere in the Universe (AND the Cosmos). See the listings for "present...(et al)".
