The one thing about this “fight” is no one seems to define the range of Young. While disconcerting this Strawman fight is metaphorical to getting rid of an idea before it gains hold. Would Young not be up to 500,000 years? This issue regardless of gaps is YEC should be FEC. 6000 years is not even to birth yet. Obviously we tend to overlook the point that God created a mature universe, not a baby big bang. Both sides want to view the beginning in some type of anthropomorphic womb without any creator at all. Then both sides try to use science to argue this wrong assumption all are ignoring.
Genesis does not state the universe started from a small “big bang” to it present size. Nor does Genesis even imply that the universe was created 6000 years ago, because it leaves out thousands of years of history. Not the years, but every detail that has happened over the last 500,000 years. Which is still YEC. Even half a million years is only a minute time interval in a universe that is allegedly 14 billion years. I understand the need for flat earthers to rebel against both sides and their irreconcilable head butting. It tends towards being a combination of historical thinking and modern simulation theories. The ancients viewed God in religious terms. With the advent of mass Exodus from religion; having a more science fiction God, goes hand in hand with our understanding of culture and human imagination. Religion was as much human imagination as current technology and it’s science fiction imaginations. No matter how one tries, one cannot escape culture and the evolution of human thinking and imagination.
One reason given about Genesis and the point of a mature universe is God was leaving us in the dark with deception. No, a thousand times no. It is Faith. A creator who set it up so humanity was God on earth, perhaps even 500,000 years ago. Where perfection was the rule. Perfection of humanity with God, not geological stability. Nor were animals and plant life elevated like they are today with a status sometimes more important than humanity itself. Not that humanity itself felt the need to be in charge, but because God lived in this universe through the image of humanity. This would not rule out that humanity itself was capable of terraforming the earth. The death and life of plants and animals was natural not the definition of death and destruction of value we have today. It is all in the interpretation of the data, not the data itself.
Faith happened due to the Fall of Adam and separation from God. There was separation, because we have a brief account of a before and after. Faith not imagination is God’s intent. Imagination leads to deception. The reason for the Flood being literal is that it was the historical record of a loss in human history. Any detail of humanity was lost to those after the Flood. It was not the transforming geological event, as much as a new history of human kind and any history before has been removed from current understanding. For the main reason that it was the end of God’s image on earth, and Faith in full effect.
