This is not only about creation. It's also about sin. There's also the promise of salvation (Genesis 3:15).
Even in the darkness of sin, there's a glimpse of the light that will come. God created us. He has not forgotten us. He has sent His Son for us. He has not left us in our sin. He has delivered us. We have just a hint of this here - "The seed of the woman shall bruise the head of the serpent" (Genesis 3:15). There is enough of a hint to persuade us that there are better things still to come. We do not get bogged down in sin. God is calling us beyond that. He is calling us on to salvation. He is calling us to come to the Saviour - our Lord Jesus Christ.
