The Greeks were the first, to my knowledge, who discovered the need for mathematical proof. Egyptians, Babylonians, etc. probably knew about the pythagorean theorem, but they didn't prove it or felt that they had to (that we know of). FWIW, Pythagoras's connection to the theorem is also disputed, but here we might just be dealing with a lack of sources. The first known proof appears in Euclid's Elements. > There is no need to refer it to his name [...] Due to the highly abstract nature of maths, names in mathematics are often very arbitrary, and the first thing that sticks, sticks. Fields are called "bodies" in German, but they denote the same thing (and both of these labels are very arbitrary). There's multiple things that get called "ring" and have nothing to do with each other. And many objects or theorems are named after people who had little to do with them due to misattribution, for example, Pell's equation has nothing to do with John Pell. FWIW, there are many things named after Indian or Arab mathematicians, and there is also the (rather important) "Chinese Remainder Theorem".
