I agree with you that the theory doesn't explicitly deny God's existence, however making everything contingent on time, chance and matter implies a denial of God. And while "evolution" may not deny God, many evolutionist do because they understand the implications of the theory.
I would point out that the theory of evolution nowhere says that evolution depends on chance. It depends on natural laws. Is it not possible that God created the laws of nature? As far as time goes, time depends on your reference frame. It is possible the the six days referenced by Genesis would be measured as tens of billions of years from our frame of reference. (The extremely high gravitational field in the early universe in the first moments after the big bang would cause a difference in measured time intervals.) A time frame of billions of years, therefore, is not inconsistent with the Bible. As far as matter goes, if God caused the big bang, He created matter. Since He created matter and the laws of nature that matter obeys, there is no problem with evolution. It simply occurs according to the Divine plan. I would agree that many people have used the theory of evolution to support an atheistic point of view. IMHO, these people are simply unjustified in doing so.
