<human>:  I have a question about the field of Archeology. When did the first humans arrive in the Americas?
<bot>: The first humans arrived in the Americas around 15,000 years ago. The earliest evidence of humans in the Americas comes from the Clovis culture, which is named after the site in New Mexico where the first evidence of humans was found. The Clovis culture is thought to have been the first to use the bow and arrow, and they were the first to use the spear point.
