The light is Christ, so in a sense this is a correct observation. However, you may be looking at Genesis as a surface text. Many people read Genesis, and the rest of the Bible as well, and do not know that the Bible is written in parable form, meaning the words have an interpreted spiritual meaning. We read about the fact that the words of God's mouth, the law (which is the Bible) are written in parable form in Psalm 78: "Give ear, O my people, to my law: incline your ears to the words of my mouth. I will open my mouth in a parable" The Bible will not be understood unless you realize this. We read again, in Mark 4 that "But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples." The chapter goes on to explain that unto those who are saved it is given to understand the parable meaning of the Bible but to those who are unsaved (without) all things are done in parables but they do not understand. They encounter the Bible but it is a parable and they can't understand the interpreted meaning. The book of Genesis, for example, talks about how God planted a garden. But the Bible says that a garden is God's spouse, in other words a garden is the true believers: "A garden inclosed is my sister, my spouse". The Bible also talks about the tree of life in the midst of the garden. We find that God refers to people as trees in parable language in the the Bible and that he 'plants' true believers. We also find that it is Jesus who is in the midst of his people in the Bible. Hence, we can understand, one hopes, that the tree of life in the midst of the Garden is parable language for Jesus in the midst of his people.
We find living creatures mentioned in Genesis that the the waters (the word of God) brought forth abundantly and God saw that this was good. Even so, the living creations of God that the word of God brings forth, that is the true believers, are good in the eyes of God thanks to Jesus. The creation of true believers belonging to God would not have been possible without Christ (the light) going to the cross and then being resurrected, so yes, the light comes first to make the true believers possible. Adam, a picture of Christ, went into a judgment death involving his side (a deep sleep in parable language) in order to create Eve, a picture of the living true believers.
