Indigenous Peoples Day: Much to Learn

 I live in Cerro Gordo County, Iowa, native home to the Winnebago and Sioux tribes. Today is Indigenous Peoples day in over 12 states, including Iowa. There are 574 recognized tribes in the United States. Columbus Day has been recognized as a federal holiday for a long time. President Biden has proclaimed, for the second year this is Indigenous Peoples day. In Canada, indigenous people are called "First Peoples" and say "the Encounter" not "Discovery." How can one discover people who already existed? I need to learn from indigenous people and "discover," what I don't know. I plan to do that.
