They were an ancient egypto-nubian race that sailed over here after a war with barbarous caucasoid hybrids from the Mediterranean decimated their population, particularly the young men and women. They had no choice but to send their older men out on a survival expedition, but before they did that they altered their genes in order to mask their intentions because this voyage of course had to be kept secret. Not only that, but they also had to manufacture an entirely new language in order to avoid detection lest their true identities be exposed and their plans foiled. No records were kept of this voyage, the only thing we really know is that when they arrived in the Americas they were greeted by a savage people in desperate need of civilization. These great civilizers, who because of their advanced age, knowledge, and wisdom were called "Old Macs," or "Elder Macs" by the straight haired savages, would eventually become known as the "Olmec" over time. The rock sculptures were cut to honor these old macs from Egypt, whom the savages considered to be Gods.
