>Because of the bigfoots, or because the caves themselves are dangerous?
Both.
> Because the bigfoots certainly survive it, so it can't be the caves. 
Lmao no. They're strong and agile as all great apes, have more durable bones, have nightvision and great senses. Google cave exploration and behold the death count. It's as dangerous as climbing top mountain peaks even when fully equipped.

Onto samefagging bait which every bigfoot thread is shilled with. It's a hominid. A bigger, smarter gorilla.

>Strong and agile as all great apes
Debatable: bonobos and humans aren't particularly strong.
>More durable bones
Hominid bones don't upgrade like some pokemon game
>nightvision
Apes have trichromatic vision: we don't have 'nightvision' much less are adapted to seeing well at night. Its not biologically possible.
>great senses
Every wild animal has more alert senses than humans, it isn't a superpower.

Can you point to a single primate species that's adapted to living underground, even for just migratory travel?

>Hominid bones don't upgrade like some pokemon game
Humans downgraded with gaining porous bones for mobility. Gorillas bones are more dense which allows more muscle mass. In exchange they're bad at swimming.
>Its not biologically possible.
For what reason? There are nocturnal primates. I agree that you cant see if there's no source of light at all, like underground.
>Every wild animal has more alert senses than humans, it isn't a superpower.
It is, if it's attached to an intelligent animal.
>single primate species that's adapted to living underground, even for just migratory travel?
What's that supposed to prove? There's new precedent for previously unprecedented every once in a while. 
>even for just migratory travel?
Here is a primate species hiding from danger underground.

>Durable bones
You're mixing up muscles with bones: bones aren't more durable; the muscles surrounding them can vary quite wildly. That's why a chimp has the same bone strength as us but can ruin anybody's day and your average man can benchpress a bonobo.
>Nocturnal primates
The reason being great apes all possess trichromatic vision: we're physically incapable of having 'nightvision'.
There is a few species of nocturnal primates but they're limited to maybe a dozen niche species. There are no nocturnal apes.
>Intelligence
Depends on which folklore you're following: are you talking the tree banging savage that can't even make basic stone tools or those reports of bigfoot wearing everything from 'monk robes' to overalls? Again being alert isn't a superpower.
>Underground adaption
Its to prove there's zero evolutionary pressure for a tree-dwelling omnivore to suddenly live underground; can you find a single primate species that's evolved to glide? Live underwater?
>Blind ape hiding in dark cavern =/= adaptation
You're saying monke man doesn't look even close to a person face-wise; he'd look like a botched Tarsier with his eyes taking up most of the real estate. Including his brain.

There's always a first.

Why would it need to?

Who?

Stellar Sea Ape kek.
>Tarsier with his eyes taking up most of the real estate. 
If you google domestic cat skull or Galago skull, you'd be right.
But google a larger nocturnal animal like tiger. The larger the skull, the proportionally smaller eyes that allow low-light vision can be. And Bigfoot have very large skulls. Which I aggree wouldn't help them in complete absence of light, like in caves.

>Bones
Sure we're spongier, can you prove a magical monke man's bones are more durable than a chimps?
>There's always a first
So you're just handwaving the reality that ape vision is incapable of night vision and there are no nocturnal apes?
>Why tools?
Intelligence would have to be displayed in order to be suggested. Octopi make tools, chimps make tools, dolphins make tools, birds make tools, even elephants make flyswatters. If bigfoot is so magically smart, how come there's no trends of them being seen with slings, atlatls, cordage, bark clothing, pottery, spears (even sharpened sticks)?
>Who?
Primates. You understand evolution right?
>Stellar's Sea Ape
A Northern Fur Seal is a primate??? Did you even read his account?
>Not knowing what a tapetum lucidum is
I'm going to explain this as simply as possible. Apes are trichromatic and diurnal. We do not possess a tapetum lucidum. That's why tarsiers and night monkeys have such big eyes to make up for that. Again: you're describing a fugly tarsier with a not-so-large brain. 
Anime facial proportions are not realistic for hominids.
