What is man made and what is naturally available?

My wife (Nandini) and son (Advay) had a unique conversation today.

Advay: Amma, is wood made of cloth?
Nandini: No
Advay: Is floor made of cloth?
Nandini: No
Advay: Are plants made of cloth?
Nandini: No

This goes on for a while. Then he switches gear:

Advay: Is wood man made or naturally present?
Nandini: Wood is naturally present, furniture is man made
Advay: Is floor man made or naturally present?
Nandini: The stone we use to make the floor is naturally available, but we make tiles out of stones and lay them here.

After a while, Advay gets a hang of whats man made and whats naturally present.

Nandini: Now, I will ask.
Advay: Ok
Nandini: Is table man made or naturally available?
Advay: Man made
Nandini: Are plants man made or naturally available?
Advay: Naturally available…. Now I will ask.
Nandini: Ok.

The question he asked next, my wife wasnt sure how to answer.

Advay: Is God man made or naturally available?

Nandini goes into a deep philosophical thought after that. She gives some answer about how idols are man made and how we call the force that creates nature as god and so on. Advay is not convinced by the answer. He moves on with his games.

After all this, I was reminded of this poster:
