I guess without guns, without anti-biotics, without decent shelters, without agriculture, they were simply busy surviving lions, lack of reliable food supply, covid-18 (lol), the ice age etc.

Would you sit around some cave camp fire, shivering in the dark for 290 thousand years or would you have gotten off your frozen butt and done something about it?
Remember, if humans disappeared today, our ‘civilization’ would be dust, sky scrappers and all in 10,000 years. In 50,000 years, the dust would have been recycled many times. Then add in a world wide ice age scrapping off whatever remained, then the ice melting and drowning the very place where most people live - the costs and rivers - under hundreds of feet of mud and sediment.
It only takes 6000 years at most for a civilization to arise. Then, if every one failed and collapsed at 6,000 years, they would be gone after another 10,000 years passed. So that’s 16000 years. 293,000,000 / 16000 = 17 civilizations arose and gone before ours being the 18th.
just think about it before piling on.
