<human>:  When did humans first start to move from place to place?
<bot>: The first humans probably moved from Africa to Europe about 60,000 years ago. The earliest evidence of human presence in the Americas dates back to about 15,000 years ago. Humans were the first to develop the technology to move from place to place. Humans began to move around the world during the last ice age, when sea levels were much lower. This is when humans developed boats and ships, and they began to explore the world.
