[$\displaystyle \forall$x$\displaystyle \in$D, A(x)] $\displaystyle \Rightarrow$ [$\displaystyle \exists$x$\displaystyle \in$D, A(x)]

If you were to define your own domain D and predicate A, how would you make this statement false?

My interpretation of this is:

Let D be the set of humans and A(x): "x is alive".

If all humans are alive, then there is a human that is alive.

I have no idea how to make this statement false.
