Sorry but your ancestors were regularly getting eaten alive by wild animals a few generations back (heck it's still an existential threat to some people). People had to resort to canibalism to survive famines. Plague, TB, polio. Just a hundred years ago there was ~1 in 100 chance a woman would die during childbirth. >40% of kids would not live to age of 5 in 1800s
The only reason you were brought into this world is because your ancestors went through shit you can't even imagine, had children, some of which survived to eventually have you.
