3. The Dighton rock carvings
Ancient carvings and paintings are fascinating and often hard to decipher. But most of them are ultimately cracked. No ancient carvings have baffled researchers more than the Dighton rock carvings in Taunton River in Massachusetts. The carvings are an odd visual depiction. They seem more like small objects rather than letters. Since their discovery around 300 years ago, their meaning is still to be found.
In 1963, with State’s permission archeologists removed the boulder and preserved it. Some believe they are the earliest markings of Native Americans while those with wilder imaginations attribute them to ancient Phoenicians.
Before you ask, yes of course some people suggest they are alien in origin and were left by aliens who visited earth thousands of years ago! – What do you think?
