“The law that entropy always increases holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations - then so much the worse for Maxwell's equations. If it is found to be contradicted by observation - well, these experimentalists do bungle things sometimes. But if your theory is found to be against the Second Law of Thermodynamics I can give you no hope; there is nothing for it to collapse in deepest humiliation.” ― Arthur Eddington, New Pathways in Science

Entropy is always increasing in a closed system, but locally it can decrease, if energy is supplied from the outside. Us evolving on Earth comes at the expense of increased entropy of the Sun.

> Entropy is always increasing in a closed system

Only if that system isn’t already in thermodynamic equilibrium. A closed system that reaches thermodynamic equilibrium has maximum entropy.

Why the universe as a whole didn’t start out in thermodynamic equilibrium, i.e doesn’t have maximum entropy is something we don’t understand.

I read a theory that life in the universe might be favorable because we increase entropy so much.
