It blows my mind that there were stone tool making hominins over 3 millions years ago, well before the first human species.
Just thinking about this point for a second is really mind-blowing especially when you think about it with the added context that up until about 200-300 years ago, human technology levels were probably closer to the stone-tool wielders than it is to modern humans in an EV listening to music through a smartphone and navigating by a global satellite system.
