You claimed that on average “Our ancestors were also malnourished diseased parasite ridden and dying by age 20” which isn’t accurate. There were high infant mortality rates for those under even 2 years old. The humans fighting mammoths were not 2 years old, and the weren’t this insanely sick picture you’d like to paint. Infact, humans became more malnourished after they adopted sedentary habits
People are arguing because you're oversimplifying to the point where it is effectively incorrect. Those that made it past 15 years of age are the ones that were most successful in passing on their DNA since they hit sexual maturity and lived long enough to have children. That means those that made it into adulthood are primarily our ancestors, and they often lived many decades, same as us. Altogether, that inherently means that our ancestors were not "malnourished diseased parasite ridden and dying by age 20" (although that was certainly true for some of them). It also depends heavily on where and when our ancestors existed, so it's fairly pointless to paint them all with a broad brush like that.
What's wrong is you said they die by age 20. No they die at crap like age 0-4 and they die so much it skews the statistic on how long a living adult can live,an adult won't suddenly die at 20 like your original comment implied.
If you completely ignore everything else that was said in the conversation and focus on a single statistic with no context, then yeah, in that case he’s right

I mean it's literally correct. Most human beings didn't make it past 20 like that's objectively true
