Yea exactly what I was thinking. I guess I should have rephrased my question to “how could someone prove their worth” in this hypothetical scenario

10,000 years would be pre-agriculture in most places. You could show them how to plant and tend food, I suppose, if you're a halfway decent gardener. Would take a while to bear fruit, though - literally.

You might be an entertaining novelty if you started singing any of the thousands of songs you probably know. They would never have heard the melodies before.
