Meh. Genesis is consideably less pertinent to eternity than the life and resurrection of Jesus Christ. There are no witnesses to Creation.
If you don’t believe Genesis, how can you believe the rest of His Word?
Genesis is completely pertinent to eternity and the life and resurrection of Jesus.
Paul refers in his writings to the first Adam and the second Adam. He says in Romans 5:12 that through one man (Adam) sin entered into the world. It is the second Adam (Jesus) who came to destroy the works of the devil (1John 3:8)
If Adam isn’t a historical figure, then Christ came, lived a sinless life and died a horrific death based on a “creation myth”.
Jesus himself said in Matthew 19:4-5 and a parallel passage in Mark 10:6: “Have you not read that in the beginning, God made them male and female”.
If you are a disciple of Christ you should trust in what He said.
