What are two possible theories about how people first settled in the americas

The one I remember is that vikings landed in america way before the europeans did. there is only a little evidence of this because artifacts were found in the soil.

Explanation:

"the royal proclamation of 1763"

monarchy doesn’t have to have the hereditary element. there have been elective monarchies in the past where you choose your king-for-life and when he dies elect someone else for the job.
