Evolution should not be treated as the explanation to creation solely?

[NaturalBornKieler]

Your premise is not entirely correct. Atheists do not "use evolution as a way to discredit religion". Evolution does not discredit religion, it discredits creationism.

Evolution is a very simple principle, based on mutation and selection. It is NOT systematic - it is the very opposite. Evolution is unpredictable - ANYTHING can emerge as a new life form due to the mutation part. But the selection mechanism makes sure that only successful mutations make it in the long run.

When a random mutation happens to be very successful, a radical change of a biosphere can happen in a rather short time. Why not?

You are right that evolution should not be treated as a definite fact and final truth - simply because there are NO final truths in science. Science does not stop there. Evolution is the present state of science and widely accepted as such. But research goes on, new mechanics and principles and details are found, tested, discussed and reviewed every day.

Evolution is a fact. Organisms evolve and this is observed. It is as much of a fact as the fact that when you drop something it'll fall to the ground.

the THEORY of evolution by natural selection explains HOW it happens, and it isn't "fact" in the strict sense of the term, but it is an explanation that is backed by mountains of evidence.

Also, the existence of the fact of evolution doesn't automatically disprove creation. God could have technically created the first self replicating molecule. What it does discredit is Adam and Eve and the idea that god created all the animals at once.
