during this era ______ no humans lived in Washington.
My class is talking about the Plateau and Coastal Indians if that helps a little.
People probably began living in the state of Washington about 11,500 years ago. This was in either the Mesolithic or Paleolithic Era. Probably the answer you need is Palelolithic.

To determine the era during which no humans lived in Washington, we first need to understand the history of human habitation in the region.
The Plateau and Coastal Indians inhabited the region that would later become Washington State for thousands of years. They had a rich and vibrant culture, relying on fishing, hunting, gathering, and trading with neighboring tribes.
However, if we are looking for a specific era when no humans lived in Washington, we need to go back in time before the arrival of the first human inhabitants. The era we are referring to is the prehistoric period, specifically the time before the arrival of the first Indigenous peoples.
To determine this era, scientists rely on archaeological evidence such as fossils, artifacts, and geological data. Through careful examination and dating techniques, they have determined that the first humans arrived on the North American continent approximately 15,000 - 20,000 years ago during the Late Pleistocene era.
Therefore, the era during which no humans lived in Washington would be the period before the Late Pleistocene era, which includes the Paleolithic and Mesolithic eras.
It's important to note that the specific timeframe can vary depending on new scientific discoveries and research. However, based on current knowledge, this is the general understanding of when humans first inhabited Washington.
