This Fox News article says an aluminum metal part discovered in 1970 is 250,000 years old (and then conclude it must be from an alien craft.)

Now tests at a lab in Lausanne, Switzerland, have revealed that the strange fragment of metal is made up of 90 percent aluminium and is 250,000 years old.

Aluminium was not produced by mankind until about 200 years ago

Is it really 250,000 years old?

    There is a huge difference between "is this thing really this old and made of aluminum?" and "was this a part of an alien craft?". Perhaps you could limit the question to validating the authenticity of the find, and avoid the speculative part about aliens? – Alexander O'Mara Oct 25 '16 at 18:16

    That thing is also referred to as "Aluminium Wedge of Aiud" and is mentioned a lot in the ancient alien believers community. Google it and you will find tons of other claims. – Philipp Oct 25 '16 at 21:48

    We need to find the "lab in Lausanne, Switzerland" to see what tests were (allegedly?) done. – GEdgar Oct 25 '16 at 21:52

    Does anyone know what particular measurements can tell us the age of a piece of aluminium? I don't know of any. – hdhondt Oct 26 '16 at 2:45

    Fox can claim that the aluminum in the object is over 6 billion years old, and they would not be wrong. weather or not the structure is 250,000 years old is another story. – tuskiomi Oct 26 '16 at 17:29
