The oldest pieces of evidence (rock paintings) for the use of the throwing wood exist of the Young Palaeolithic Age (approx. 5000-1800 BC); since then constantly used until the pre-Christian ancient world:

In the Cretan-Minoic Region ( ca. 2000 BC): Sign of rank and dignity of military leaders. In Greece commonly used weapon with the term "lagobolon" = hare club, hare thrower.

The throwing wood is not proved to have been used by the Romans (from approx. 500 BC), only for the rural population´s hunt of hares. The Cateia seems to have been a crooked weapon with the characteristic ability of returning -ergo a boomerang- which was used by the Gauls and the Teutons (from approx. 100 AD).

For the North, the use of the boomerang is proved for the bird hunt, approximately at the times of the Goths (from approx. 100 AD).

Northern Scandinavia: Throwing wood known since the Young Stone Age (approx. 5000 BC).

The Urals: Finds from the time of 2000 BC

Poland: Surely the oldest find from the:
"Olazowa Cave" in the "Polish Carpathians"
Germany: boomerang find in the:
Elbschottern near Magdeburg (approx. 800 - 400 BC).
The origin of the throwing wood remains unsolved. That it was introduced by cultures outside Europe is unlikely, but an influence from the ancient Orient (Near East) is probable.
