That depends on why they believe those things but general terms that may apply include atheist, pragmatist, materialist and skeptic.
Everything but gods and supernatural superstition.
A person who believes there is no God is an Atheist, BUT one can still believe in evolution and believe in God. One way of believing both of these is that God still chose when and how each species would evolve and that before Adam and Eve evolved that He gave them a soul.
Evolution is an ongoing process that will continue as long as life exists. As long as organisms continue to reproduce and environments change, evolution will continue to shape the diversity of life on Earth.
Spiritual aspect, is about how you communicate to God, and believing that God exists.

Some problems are unstructured in that similar problems have not occurred before and no ready routine exists for problem solving. Other problems have occurred routinely and a decision process exists for the problem.
There's vast amounts of evidence of Jehovah God's existence. Here's 2 big ones: 1. Creation/nature. All throughout nature, there's consistent examples of things being born and or made by a collection of existing particles and circumstances. Never has there been something that has come from nothing; In all scientific observations, there has always been something that was responsible for something else. (Hence energy always being in existence; it can't be destroyed once created...) It would make sense then, that a being with access to this energy (as well as being responsible for its creation) would be able to live an eternity into the endless past. When you consider everything that exists in nature, even to our limited (yet growing) knowledge, for someone to have created everything, they would need to have more power, intelligence, and longevity than anything in existence. By definition, in the very least, this individual would be considered god-like. It would make sense also then, that this being would deify themselves in the eyes of their creation (a.k.a. make themselves 'God'), leave record of His dealings with mankind throughout history (the Bible), as well as have a way of communication with His creation that would be outside the norm (prayer). 2. The Bible. The book has been preserved throughout the centuries, despite people trying their best to snuff it out, keep it from being interpreted, even altered. The original, accurate message left in its pages is still able to be received by those that want to know it. In addition, there's no way that a small group of men, many of which had never met, could convince worldwide society (who they knew would be here and not taken out by either their own hands or an extinction level event), to act in a way that's detrimental to society. This is exactly what the Bible prophesied would happen. (Matthew 24:4-17; 2 Timothy 3:1-6) (New World Translation of the Holy Scriptures)
If you believe in God, there a many events that can help you to continue believing he is there. The miracle of birth and life is a major sign that God exists to many people.
Evolution doesn't take 4.2 billion years. It takes forever and no time at all. Where life is, there evolution is happening, and it will continue to happen as long as life exists.
One word: extinction. As long as life exists, organisms will reproduce with variation - which means per definition that evolution will occur. The only way for evolution to stop happening is for life to cease existing.
