As a programmer, I'm ashamed to admit that the correct answer is no. If zero was natural we wouldn't have needed 10s of thousands of years to invent it.
Did we need to invent it, or did it just take that long to discover it? I mean “nothing” has always been around and there’s a lot we didn’t discover till much more recently that already existed.
As a programmer, I'd ask you to link your selected version of definition of natural number along with your request because I can't give a fuck to guess
I think you're considering whether zero is somehow "naturally-occurring", while others may be considering the concept of a natural number, which is a nonnegative integer.
