As Phil mentioned the Hebrew word for good implies suitability for its created purpose, not necessarily completeness or perfection. Notice that even though Adam was part of God’s good creation, it wasn’t good that he was alone, even before sin. I believe all of creation is moving toward God’s perfection. In the Bible this is the idea of shalom, the peace and justice that characterizes the rule of God. In the ANE “rest” was associated with a diety or ruler’s reign. Some people see the creation story as paralleling the inauguration of a temple. In this case the whole cosmos is the temple of the one true God and when he takes up his rest on the seventh day, he isn’t quitting or relaxing, he is signaling the beginning of his reign over creation. See this short video by Bible scholar John Walton if you want more background on that: https://www.youtube.com/watch?v=CTKD9ioLLwk&feature=youtu.be
In the Bible perfect shalom is not fully inaugurated until the Eschaton, the return of Christ and the New Creation. So I see evolution as very compatible with the idea that creation is moving toward its “telos” or fulfillment, but it will never be “perfect” until Heaven unites with Earth and God comes to dwell with his creation. The development of evolution is a similar idea to what is seen in some of the imagery of the Kingdom in the parables of the New Testament. Like when a small seed matures into a great tree. I think all of creation is still “maturing” under God’s rule as his Kingdom comes on earth. As humans we are part of God’s good creation in that we are suited for the purpose God calls us to, bearing his image and being faithful stewards of his creation and ambassadors of his Kingdom. But we still need to be conformed to the image of Christ to fulfill that created purpose.
I think one major difference between the young earth interpretation and the evolutionary creationist interpretation concerns the idea of the Fall. I believe that sin entered the world and separated humanity from God, and that had profound effects on the human spiritual condition going forward for all generations. Human sin also affects the flourishing of other creatures and damages entire ecosystems. But I don’t think human sin fundamentally altered the created order or the laws of nature. I don’t believe human sin changed peaceful herbivores into predators or caused deadly viruses to spring into existence or initiated tectonic activity. The young earth interpretation requires God to essentially re-create the world in fundamental ways when Adam and Eve eat the fruit, and I find this view problematic for lots of theological and scientific reasons.
