The water level of the oceans, thus exposing a land bridge.
Scientists believe that during the last ice age, around 15,000 to 20,000 years ago, people migrated from Asia to the Americas by crossing a land bridge that connected Siberia to Alaska, known as Beringia. As the ice age glaciers locked up water, sea levels dropped, creating this land bridge that allowed for human migration.
Climate played a role in people migrating to the Americas during the last Ice Age. As the climate warmed and ice sheets retreated, land bridges formed, allowing for easier migration from Asia to North America. This aligns with the timing of the first human presence in the Americas.

Although many people think that there was a bridge for that purpose, I doubt there is. If their was a bridge they would have been destroyed and sunken into the ocean. If there is to be one then it would have to go deep into the north pole and back into the Americas.

The criollo or creole people, who were people of European ascent born in the Americas.
Yes they did, in order to go to the Americas they crossed over a land bridge between Russia and Alaska(present day).
During the ice age, the sea level dropped and people crossed by land
Wherever the bomb is dropped a lot of people will be killed during the explosion and more from radiation for a long time after. Immediately after the bomb is dropped we will do what we have always done as Americans and go kick some a**.
About 900 million people live in the Americas.
