Can one take quotient by finite group in the category of schemes? Will the singularities be visible? For example, it looks like $\mathbb{C}/\{z \sim -z\}$ is isomorphic to $\mathbb{C}$. What about complex analytic spaces - can we take quotients by finite groups and are the singularities visible?
From the comments, I know that quotient singularities are visible on schemes/analytic spaces of complex dimension $\geq 2$. Are there examples of quotient singularities on curves?
