Can Darwin's supporters answer this ?

creationism can easily coexist with evolution. it does not have to be one or the other.
as far as quran talking about minor things, sure but does it talk about everything, did quran mention dinosaurs? or the skeletons of previous species. the aforementioned homoerectus or homohabilis, neandrathal, etc etc

no one is sayong god did not create the universe, but I dont think it is for you or I to limit what god can and can not do or how he can go about creating the universe.

as far as rejection of darwin's theory, sure..many reject it. but something being rejected by many does not make it a fact. theory of evolution is a theory, just like theory of everything being created from scratch in its current form is also a theory that leaves many unanswered questions and has no answer for simple things like environmental mutations

Allah does know best, and nothing in the Quran is explicitly against any sort of evolution.
