Atheists would rightly consider the evidence, conclude there was a creator, but give it no due reverence because they would conclude (rightly) that none is morally due.
As for the 'correct' conclusion that none is due, that is itself an awfully confident statement about a deity you know little about, even whether it exists. Some might consider the fact that we are left alone, rather than driven like puppets in some manner, to be a positive factor on its own, after all. You may not like that we are not handed a life of total goodness and light and luxury, or whatever your ideal universe looks like, but it could also be a great great deal worse.
Concluding there is a creator, simply transforms one from being an Atheist into something completely separate.
