If you discover a flat surface in the forest that happens to have some stuff on top, like pine-cones or whatever, you might think to yourself: "Hah! It's a table!", even if no human ever touched it or designed it to be a table.
Similarly, if we find aliens and see their tables, then we would also call them tables even though they were not human-designed.
If an AI builds and uses a table, then that is still a table, even if no organic (or even conscious!) being ever intended it to be a table.
Last but not least: tables don't even have to be made of matter! A table is a table, even if it's in a computer game or virtual reality.
These concepts are much more fuzzy around the edges than philosophers like to pretend they are.
