God creates in an ordered way - light and dark, night and day, land and sea - his creation is structured to work in a certain way. If I jump in the air I know that gravity will pull me back down again just like it did yesterday and will again tomorrow. As I inhale I know that oxygen will be absorbed into my blood cells and that carbon dioxide that my cells have created as a waste product of respiration will be releases as I exhale. I can only live my life because of God's ordered creation. Every breath, sip, step, word and glimpse is possible because of the way God created.
As God creates, he declares everything He creates is good. When I experience 'goodness' in life, nature, relationships, sights and sounds I am seeing God's fingerprints in His creation.
