If your parents didn't have kids, you wouldn't have kids either.

WOW, you are a genius, I never thought of it that way!

I know, I know.

My parents didn't have kids; I was assembled from a mail order kit.

I told my sister this and he asked about adoption. I think that "having kids" includes adopting them.

The problem is that "have" means both "possess" and "create" in English. For extra fun, consider that it can also mean "eat", which is the inverse; if your parents ate you, you're not likely to continue the family tree.
