Why don t we live in caves anymore?
We don't find a lot of evidence of habitual human habitation of caves. Caves are terrible places to live. They're dark, ventilation is bad, the temperature is often unpleasant, and if you try to light and warm the place up with fire, that ends up exacerbating the ventilation issue.
When did humans stop being cave people?
Paleolithic is Greek for “old stone.” Scientists say this period of time began about 2.5 million years ago and continued until about 8000 B.C. The Mesolithic Age is when early humans still hunted and fished as the basis of their existence but also started to use new ideas such as bow and arrows, nets and spears.
Did people live in caves 5000 years ago?
This era extends from more than 2 million years into the past until between 40,000 and 5,000 years before the present. The image of these people living in caves arises from the fact that caves are where the preponderance of artifacts have been found from European Stone Age cultures.

Living in a cave can be dangerous due to a variety of factors, including the risk of cave-ins, lack of ventilation, and exposure to wildlife and natural hazards.
Why are Neanderthals not human?

Did cavemen live long?
First and foremost is that while Paleolithic-era humans may have been fit and trim, their average life expectancy was in the neighborhood of 35 years. The standard response to this is that average life expectancy fluctuated throughout history, and after the advent of farming was sometimes even lower than 35.

Yes, they looked a lot like modern humans and were closely related to us, but, as you might expect, had some relatively minor genetic differences. Europeans, for example, seem to have mostly been darker skinned than today, and some other traits, like adult milk tolerance, had not yet spread through populations.
Is there oxygen in caves?

Can you live in caves like early humans?
The stereotypes are true. Stone Age people really did live in caves – though not in the way you might imagine. Our ancient forebears didn't simply crawl to the darkest spot and call it home. Rather, they constructed shelters in the mouths of caves and lived there.

Answer and Explanation:
Adam and Eve were not Neanderthals. Although evolutionary biology contradicts the story of Genesis, this answer will assume the two were compatible. Neanderthals were prominent in modern-day Europe; they were smaller populations across parts of West Asia.
