There are a spectrum of beliefs between "pure creationism" and "pure evolution". Organizations such as the "Institute for Creation Research" (ICR), the "Creation Research Society" (CRS), and "Answers in Genesis" (AIG) believe God created during six literal 24-hour days, the earth is young, and the global flood was a real event.

Organizations such as "Reasons To Believe" (RTB) believe that the days of creation are long periods of time, but consider themselves creationists because God started the process and intervened along the way to introduce new types of plants and animals. They believe in "pre-men" that later became human only after God gave them a soul. This view is known as "progressive creation", a type of "theistic evolution". There is a slight difference - theistic evolution is creation by continuous evolutionary processes started by God. Progressive creation is similar but says that God intervened occasionally to do "mini-creating" when necessary to keep things going.

There are people who believe that God exists but that atoms-to-people evolution is true. God basically "wound up" the universe and let it go. This "god" for many is not the personal God of the Bible but a distant, impersonal one.

Finally, true evolution is really an atheistic philosophy and has no need for any type of God, even an impersonal one. Proponents may still use "God-talk", but their "god" is some type of creative force that is an (as yet undiscovered) property of matter (like the "force" in the Star Wars movies).
