comment Is every complex (smooth) manifold a scheme?
Actually, if you want $X^{\text{an}}$ to be a smooth manifold, $X$ needs to be a smooth variety. I have never seen the analytification functor for something else than schemes of finite type over $\mathbb{C}$.

comment Is this really a typo?
If a function $f$ is $C^k$ for $k\geq 1$ then it automatically is $C^1$, too. So the statement is valid.

comment Algebraic Solutions to Systems of Polynomial Equations
By 'all variables algebraic' you mean one solution will be a tuple of algebraic numbers?

comment An affine open neighborhood of a nonsingular point
No, it is not. In fact, it is a rich source of counterexamples regarding schemes that are not varieties.

comment An affine open neighborhood of a nonsingular point
Your $\Gamma(U,\mathcal{O}_X)$ is (by definition of finite type) a finitely generated $k$-algebra, not just a localization of one.

comment My sister absolutely refuses to learn math
I tend to agree with your last sentences but it is not at all clear to me whether quick learning later on is not actually also a function of having spent large amounts of time in school on the subject.

comment Theorems' names that don't credit the right people
Which is not at all wrong since the circumflex just denotes a left-out 's' from old French spelling.
