Does it have to be? If a natural rock formation or horizontal tree root with a flat top is used as a table, then it is a table, is it not?
Tables are anything humans use for the purpose of a table.
Their manufacture or lack thereof is immaterial.
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.
Incidentally, only the life created by God Himself is actual life, but the life that evolved on its own is not actually life, it lacks the substance of true life. Has nobody tried this argument against Darwin's work before?
