The Book of Genesis in the Bible and Hesiod’s Theogony are both accounts of the origin of the universe, but from different cultures. Genesis comes to us from the ancient Hebrew scriptures, and the Theogony is a poem that comes from the ancient Greeks. The two accounts vary drastically, and they have very different views on the origin of evil, the earth, the godhead, and so on.
In the Genesis chapter 1, God creates the heavens and the earth, and then proceeded to create the rest of creation over six days, and then rested on the seventh. As is shown later in the Bible, He rested on the seventh day to give mankind a pattern: to work six days and then to rest on the seventh. God is eternal, so He had no beginning and He will have no end. On the first day God spoke light into existence out of nothing. On the second day He created the firmament (Probably the atmosphere). On the third day God created dry land and plant life. On the fourth day God created the sun, the moon, and the stars. On the fifth day, God created birds and marine animals. On the sixth day God made the land creatures, and as a culmination of His creation, He created man. Evil came as a result of man’s sin, and were not in the universe to begin with.
In Hesiod’s Theogony, Hesiod claims that he got his words from the Muses, who he says are the daughters of Zeus. He gives them credit for the story, and then proceeds to tell his story. He said that in the beginning Chaos came to be. He does not say how, but according to his tale that is what happened. He says that after that, Earth (Gaia) came to be, and then many other gods. These gods gave birth to other gods, and they to other gods, and so on. Men’s blessings and curses are personified as gods. The bad things in this world are deities, and are not a result of man’s actions. Men are born into a cursed world, but it is not their fault. The earth, the heaven, the sea, and all of nature is created by the procreation of other gods, and thus are gods themselves. Hesiod does not actually speak about how man came to be in the Theogony, unlike Genesis.
A lot of differences stand out between the two accounts. One of the main differences between Genesis and the Theogony are the view of the godhead (who is over mankind). Genesis says that there is one God, and that he created the entire earth. The Theogony says that the god Chaos came to be, and then a lot of other gods came to be through procreation. Hesiod says that the evil things in the world are gods, and that mankind had nothing to do with evil in this world, while Genesis says that evil came to the world as a result of man’s rebellion against God. In Genesis, God spoke creation into existence in six days, while in the Theogony, creation came to be by the procreation of various other gods.
