Significantly more people were alive in prehistory than in recorded history. So it’s likely one or more of them were significantly injured.

This is one of those things that's probably incredibly difficult to estimate with any level of accuracy.
If 5 people took turns existing in sequence that's not more likely for a human observation than one human over that time. It only matters how many hours where humans were available to die and that's roughly matched between prehistory and the last 100 years.
Tunguska over London would have had a serious death toll where an airburst in a remote area didn’t. But you’re going to see deaths in an area with a population density of 1 per square km or 100,000/km2.
More relevant when considering the criteria of well documented evidence, a hypothetical ship on an ocean voyage in 1500 is likely to just disappear. Let alone a random West African goat herder in 2200BCE.
Given that the world population is predicted to peak at about 10.5 billion roughly 60 years from now, it also looks like this won’t change anytime soon.

For comparison there’s still 300,000 Wild West African Gorilla today and they’re extremely restricted in range, share that range with modern humans, etc.
Human populations in prehistory were believed to average somewhere in the 1-15 million range which puts 10B at the very low end estimate with 100+ billion being considered plausible. There was at least one major bottleneck but humans predate the last ice age.
PS: Calling anything history before we have any surviving text to work with is also a stretch.
I wonder if any people died as an indirect result - someone startled by the flash of light or the bang, who stepped into the path of a carriage, or just slipped and fell and cracked their skull.

However, note that when I was trying to find the original paper, that is, something more substantial than the popular news blurbs that are everywhere, I found wikipedia was less than impressed with the evidence.

Anyhow, I suspect a lot of our long term generational history gets turned into religion and legend, that is to say, the legendary events probably happened but like a good fish story the facts get shifted over the years.
