| Oct 25, 2017 at 20:21 | comment | added | R. van Dobben de Bruyn | Étale cohomology is defined for any scheme (or stack, or ...). I don't know a single reference that insists on sticking to smooth varieties. And you cannot use Frobenius to count rational points if your base field is $\mathbb Q$. | |
