Jean-Jacques Rousseau was a philosopher in the 18th century. He wrote novels and had many different theories on humans, some of which are still accepted today.
The first humans to settle in the Americas crossed the Bering Strait between Alaska and Siberia. At the time it was a plain and you could walk across.
It's commonly held that the first humans came to the Americas via a "land bridge" between Russia and Alaska during the Ice Age when it's thought to have been possible to walk across what's now the Bering Strait. So those humans would have come from Asia.
No, they only became "native Americans" after they migrated into the Americas - it follows that there were human beings before those migrations took place. America may have been first populated only around 20,000 years ago (the date is still being investigated); the first modern humans in Asia lived perhaps 60,000 years ago. The earliest modern humans (Homo sapiens) evolved in East Africa around 200,000 years ago.

The two leading theories are the Coastal Migration Theory, which suggests that the first humans arrived in the Americas by traveling along the Pacific Coast in boats, and the Clovis First Theory, which proposes that humans first arrived in the Americas via a land bridge from Asia during the last Ice Age.
The two main theories of migration to the Americas are the Beringia Land Bridge theory, which suggests that early humans crossed a land bridge from Asia to North America, and the Coastal Migration theory, which proposes that ancient humans migrated by following the Pacific coast. The main difference lies in the routes taken by the migrating populations, with one theory focusing on a land bridge and the other on coastal migration pathways.
Scientists do not know for certain why mammoths died out. Theories include climate change leading to habitat loss or overhunting from humans.
The leading theory is that humans first came to the Americas by crossing the Bering land bridge from Asia to North America during the last Ice Age. This migration is believed to have occurred around 15,000-20,000 years ago as the ice sheets melted and opened up a corridor for early humans to travel.
Some other theories humans have devised are:The Big Bang theory of cosmological expansionThe theories of general and special relativityThe germ theory of diseaseAtomic theory and quantum mechanics
Some theories suggest that Neanderthals interbred with anatomically modern humans, leading to their disappearance through genetic assimilation. Others propose that environmental factors, competition for resources, or even direct conflict with modern humans contributed to their extinction. It is likely that a combination of these factors, rather than a single cause, led to the disappearance of Neanderthals.
The land bridge theory suggests that around 10,000 years ago, a land bridge called Beringia connected Asia and North America, facilitating the migration of early humans into the Americas. This theory helps explain how humans first populated the Americas by crossing from Asia into North America.
While there are many theories, the most commonly accepted is that they walked over across the land bridge that used to exist between present-day Russia and Alaska.
There are various theories about how humans were created, including religious beliefs such as creationism, which posits that humans were created by a divine being. Scientific theories, such as evolution, propose that humans evolved over millions of years through the process of natural selection. Other theories involve the idea of panspermia, which suggests that life on Earth originated from microorganisms or organic compounds brought here by comets or meteorites.

During the last great ice age, large ice sheets locked up much of Earth's water, lowering sea levels and creating a land bridge between Asia and North America known as Beringia. This allowed humans to migrate from Asia into North America, eventually leading to the settling of the Americas.
