Creation

The creation of the universe, oftentimes simply referred to as "Creation" or the story of Creation, refers to creation/beginning of the existence of the physical plane, or universe (which is somewhat confusingly also sometimes called "creation" or "all of creation"). Per traditional Judeo-Christian-Islamic beliefs, God created the universe in six days. This is knows as "Creationism," and stands in opposition to other concepts of the start of the universe, including those related to evolution, and even "theistic evolution." (which holds that God does exist, and intelligently guided the process of evolution to where the world is today.

A significant amount of Abrahamic Monotheists that believe God created the Universe in exactly the way described in the Bible, and are referred to as creationists. Other Abrahamic Monotheists think that the biblical creation story has fundamental truths and messages, but should not be taken literally. The biblical six days of creation were as follows:
 * First day: God creates light ("Let there be light!"). The light is divided from the darkness, and "day" and "night" are named.
 * Second day: God makes the sky (interpreted as referring to Earth's atmosphere in modern times) over the earth, dividing "the waters above" from "the waters below."
 * Third day: God commands the waters on earth to be gathered together in one place (ocean), and dry land to appear. "Earth" and "sea" are named. God commands the earth to bring forth grass, plants, and fruit-bearing trees.
 * Fourth day: God creates lights in the sky to separate light from darkness and to mark days, seasons and years. Two great lights are made (the Sun and Moon, though not named), and the stars.
 * Fifth day: God commands the sea to be filled with "living creatures", and every kind of bird, and commands them to be fruitful and multiply.[7]
 * Sixth day: God commands the land produce all kinds of animals. He makes wild beasts, livestock and reptiles. He then creates the first human (Adam). People are told to "be fruitful, and multiply, and fill the earth, and subdue it." Humans and animals are given plants to eat. Then God calls his creation "very good."[8]
 * Seventh day: On the seventh day God rested.

Non-Creationist Beliefs
The Abrahamic religion that creationism is most important to is Christianity, because it's central belief that Jesus Christ died on the cross for humanity would not make much sense if evolution were true. If Adam did not sin and cause the fall of mankind, then there would be no need for a Savior to come.

Judaism and Islam have less of a problem with non-adherance to creationism, because both religions proclaim that all one needs to do to be honored by God is to be righteous and moral. The concept of a "fall" of humanity is not as pertinent to their beliefs.
