Boomer = Male Kangaroo Boomerang = Weapon designed to break the neck of Kangaroos...(Not to come back)
The oldest Australian Aboriginal boomerangs are ten thousand years old, but older hunting sticks have been discovered in Europe, where they seem to have formed part of the Stone Age arsenal of weapons. Rock art depictions of boomerangs being thrown at animals such as kangaroos exist on some of the oldest rock art in the world in the Australian Kimberly region, (dating still to be confirmed but potentially up to 50,000 years old). One boomerang that was discovered in Jaskinia Obłazowa in the Carpathian Mountains in Poland was made of mammoth's tusk and is believed, based on AMS dating of objects found with it, to be about 30,000 years old. Boomerangs are also found in Europe and Egypt. In the Netherlands, boomerangs have been found in Vlaardingen and Velsen from the first century BC. King Tutankhamen, the famous Pharaoh of ancient Egypt, who died over 3,300 years ago, owned a collection of boomerangs of both the straight flying (hunting) and returning variety. And apparently the latest Russian version has eight wheels....
I would argue that these were "throwing sticks" as you've called them...As the name, wood and target are all Australian, im claiming "Boomerang" as Australian...The others can come up with their own name... : ) hehe...
