Also, does it really matter, they never really lived that long on average anyways

I think it matters. Animals adapt to their habitual diets and most of the disorders we suffer from today are evolutionary mismatch disorders. Although mean lifespan was short by modern standards, that was mostly due to infant/child mortality.

I don’t think there is that much uncertainty. We have middens, cut marks, isotope studies, micro-ware on teeth, fossilized tooth plaque and evidence of flora and fauna associated with human habitats. Do we need to find a dietary guideline cave painting? Oh wait...

We know some things in broad strokes, but we don't even know how much energy these groups were getting from plant vs. animal foods, and data in general are limited by what has survived and what we've found.

Bayesian or frequentist uncertainy?
-
Haha, both for sure. I don't think there is any way to extract a detailed picture of ancient diets from the data that are available, although of course we do know some things.

So we don’t know if they were hunters or not? We might not know what specific species they ate at any given time, but are you saying there’s a period in human history during the last 1 million years let’s say where “humans” did NOT hunt and eat animals?

I'm not saying that

Isotope analysis of bones and teeth ?https://academic.oup.com/jmammal/article/93/2/368/920007 …

We certainly have some information. Isotopes, dental plaque, environmental analysis, middens, coprolites, etc. But putting together a detailed picture of what our distant ancestors tended to eat is beyond our current capabilities.
