In 1974, this is a wedge-shaped object found 1.2 miles east of Aiud, Romania. It was discovered on the banks of the Mures River. It was reportedly unearthed 35 feet under sand and alongside two mastodon bones. It looks like the head of a hammer and is made of an alloy of aluminum encased in a thin layer of oxide. It’s strange because aluminum was not discovered until 1808 and not produced in quantity until 1885. Since it was found in the same layer as mastodon bones, it would indicate that this wedge was at least 11,000 years old. Many people believe that this wedge is evidence that aliens visited earth, since there is no way that humans created such an alloy so many thousands of years ago.
