The Sumerians existed in Mesapotamia nearly 7000 years ago and without them we probably wouldn't have writing, maths or many other incredible inventions. But where did they originally come from and why is it so hard to find out? Tiernan and Athena look at whether these amazing ancient peoples were the excellent travellers or just beamed down by winged aliens. They'll bring the evidence so you, our Chief Detectives, can work out whether you're on team buster or team truster on this case.
