If people have been in the Americas for thousands of years, and homo-sapiens originate from Africa, how did they get there?

The most accepted manner is humans migrated from Africa, north and east through Asia and across the Northern Pacific to Alaska and then down south. During the prior ice age there is believed to have been a solid “land bridge” of ice that connected Russia with Alaska. People made it across, the bridge melted behind them (this took hundreds of years) and people eventually moved all the way to South America.
More recently, genetic research indicates that Polynesian peoples likely also made it across the Pacific Ocean via island hopping and long distance sailing and also made it to South America. This is still a recent and not universally agreed theory but genetics does suggest that Polynesian blood was mixing with Indigenous South American blood many, many years early than previously believed.
