I wonder about the evolution of words for technology

[Marthe48]

I am surrounded by electricity, electronics, time and labor saving devices. Sometimes, I imagine a person from one of the tribes that are unaware of what developed nations have at hand coming into my house and being amazed at so much that we take for granted.
There are some tribes in Brazil who were happened upon in the late 20th century, and anthropologists agreed to avoid exposing them to the world outside their domain.

I was watching an episode of Ancient Aliens, which discussed the books of Enoch and Ezekial in the Bible. The commentators believe that the wheel of fire and other descriptions denote space ships.

I started wondering how humans add words to describe technology to their vocabulary. A term such as Iron Horse came into use to describe steam engines, and we've used many Greek words to make words such as telephone. But if humans don't have words in their vocabulary to begin with and are essentially living with Stone Age technology, how do they come up with words to describe something they've just seen for the first time ever and have no experience with the components that make up, with say, a phone?

Thanks for comments.
