When did Pythagoras invent his theorem?

Pythagoras, a Greek mathematician and philosopher, is traditionally credited with the formulation of the Pythagorean theorem, which relates the lengths of the sides of a right triangle. However, the theorem was known and used by various ancient civilizations, including the Babylonians and Indians, long before Pythagoras. Pythagoras lived around 570-495 BCE, but it is unclear when he specifically "invented" the theorem, as it may have been documented by his followers rather than by him directly.
