The most widely accepted theory among scientist is that the last place humans migrated to was

South America. We started in Africaand moved to the Middle East, where some branched off and settled in Asia and others went to Europe. Some European settlers then migrated to North America, and then some of those went to South America. Note: This is talking about indigenous peoples, not about people invading, such as the British and French settling what is now the US and Canada, or the Persians invading European and Asian countries.
