At the heart of this debate is whether or not the material world was created by spirit. If the material world were not created by spirit, then everything which has occurred since the beginning of space and time are products of the material world. Everything which is incorporeal proceeded from the corporeal. There is no middle ground. There is no other option. Either the material world was created by spirit or it wasn't. All other options will simplify to one of these two lowest common denominators which are mutually exclusive.
So we need to start from that position and examine the evidence we have at our disposal which is creation itself. Specifically, the laws of nature; physical, biological and moral. And how space and time has evolved. And how we perceive God.
It should be obvious that if the material world were not created by spirit that everything that has unfolded in the evolution of space and time would have no intentional purpose. That it is just matter and energy doing what matter and energy do. Conversely, if the material world were created by spirit it should be obvious that the creation of the material world was intentional. After all in my perception of God, God is no thing and the closest thing I can relate to is a mind with no body. Using our own experiences as creators as a proxy, we know that when we create things we create them for a reason and that reason is to serve some purpose. So it would be no great leap of logic to believe that something like a mind with no body would do the same. We also know from our experiences that intelligence tends to create intelligence. We are obsessed with making smart things. So what better thing for a mind with no body to do than create a universe where beings with bodies can create smart things too.
