In the beginning when the universe (heaven) and our planet Earth were created by God, it would only be a matter of six days for creation to be finished by God (Genesis 1:1-31). Not billions of years. God created in six days for a purpose. God gave thought (intelligent design) to His creation. There is no denying it, there is great beauty in the cosmos which we have only begun to fathom. The Hubble Space Telescope has only gave us a small glimpse of this awesome universe we live in. This all started with the days of Genesis.
The six days of creation week were literal twenty-four hour days, not billions of years. The Hebrew word for “day” is “yom”. The “yom could mean several things such as a literal 24 hour day, daylight, or an indefinite period of time. In Genesis 1:1-5, it is defined as a literal day the first time it is used. Of the 2,291 times yom is used in the Old Testament, it is always used as a literal day. When used in the plural form “yamin” it always refers to a literal day. Yamin is used 845 times in the Old Testament. The context of Genesis chapter one is tight chronology and not a indefinite period of time. Yom forms the basis of our work week of 6 literal days (Exodus 20:11). So the proper interpretation for the days of Genesis is a solar (24 hour) day and not an indefinite period of time. Each literal day (evening and the morning), God did His creative acts to make the Earth to be suitable for biological life and His ultimate creation man (Adam) (Isaiah 45:18). Earth did not come about by random processes,. the odds to that is astronomical. God gave thought (Intelligent design) to His Creation and this gives us a reason to glorify Him every time we look into the night sky away from the bright city lights. The night sky is bespangled with stars. “The heavens declare the glory of God; and the firmament sheweth his handywork (Psalm 19:1) (KJV). Jeremiah 10:12 says. “He hath made the earth by his power, he has established the world by his wisdom, and hath stretched out the heavens by his discretion.”
Science expresses the universe in terms of time, space, matter, and energy. The first three verses in Genesis chapter one expresses the same. “In the beginning (time) God created the heaven (space) and the earth (matter)… Then God said, “Let there be light (energy)…” And this all happened on the first day of creation. And not over billions of years of random chance. And yes there was light on the first day of creation. He was the Light (John 1:5), until He created the physical light we call the sun and the stars on day four of creation (Genesis 1:14-19).
The days of Genesis established the First Law of thermodynamics at the end of creation week (Genesis 2:1-2). This law states that the total amount of energy and matter in the universe is a constant. One form of energy or matter may be converted into another, but the total quantity always remains the same. Therefore, the creation is finished exactly as God said it was way back in Genesis. There is no room for long geological eras within the days of Genesis. The days of Genesis are mentioned in Exodus 20:11, and they are no myth. God’s Word (the Holy Bible) is not a archaic book of superstition. God’s thoughts are above our thoughts. We cannot fathom with our finite minds. It takes faith to please God and He is a rewarder to them that diligently seek Him (Hebrews 10:6).I am sorry for them who say God does not exist (Psalm 14:1).
