I have read several books about how there is a lot of evidence that there was long ago much contact between the Old and New Worlds, and that somewhere between them, the Lost Continent of Atlantis really did exist. If the books speak the truth, then it is hard not to believe that this is at least partly true. But I would like to know if the books are giving true facts or not. Here are some of the things they say (some are not directly related to Atlantis, just other points of interest)
-there are words in languages of officially unrelated languages with striking similarity, eg. "dad" (tata, tad, ata, etc), "papilio" (Latin for Butterfly, something like "papilotl" in an Amerindian language)
-there were elephants illustrated in Maya or other Indian images and carvings. These could have been "borrowed" from Egypt, but in 1928, a skeleton of a mastodon was discovered on an archeological site's stove somewhere in Latin America
-there is evidence that long ago, amazing technology which would seem to relate only to the 20th century had been pre-invented. For example, there are stories in old Indian literature about airplanes, as well as about rockets powered by mercury (another claim being that rockets have been fired at Alexander the Great's army in India). Not only this, but the book claims that there was a weapon clearly described in several ancient Indian texts that sounds pretty much exactly like modern nuclear bombs. Further evidence cited is an excavation where skeletons were found lying in a town, with high levels of radiation, as well as other evidence of nuclear warfare in that area.
-the cro-magnon race of humankind is claimed to have been related to for example the modern Basques. Also, a tomb in Latin America contained a cro-magnon person's remains. Therefore this race is identified with Atlanteans who escaped the destruction of their island and whose culture afterwards might have regressed.
-the Canaries are alleged to have once had an indigenous population that showed various signs of being Atlantean. They didn't have boats, for fear of being swallowed up in the sea like their ancestors.
Is much of this nonsense, misinterpretation or fabrication, or is there really much truth to this?
