Archaeologists have found a clay tablet from 800 B.C., but that's not the weird part.
Literally millions of such tablets have been found.
The website Mysterious Universe says the weird part about this particular one is that it looks just like a cell phone, with carvings in the shape of buttons, in the same place that buttons go a cell phone.
Instead of numbers, it has ancient Middle East symbols called cuneiforms.
Some think the person who carved it met a time-traveler or an alien.
Many more of course think it's a plain old hoax.
