Standing amidst the waters of Brazil’s Inga River, the mysterious Inga Stone of Paraíba, Brazil is an archeological treasure of much ongoing controversy. Covering most of its 150-foot length and 13-foot height, are strange, unidentified geometric symbols, varied in size and shape, which are apparently carved into its Gneiss exterior. Although many observers have speculated on the origins and meaning of the symbols, no theory has yet been proven 100% factual. Are they a message to future generations from our ancestors? Did a previously unknown civilization exist, possessing ancient technology long since forgotten? What do the symbols really mean, who carved them, and why?
