That's the only way I can ever learn anything. If I have any advantage or knowledge to pass on here it is only because I've been wrong more often and made more mistakes than most of the members here.
Let me start with the eye but I'll try to get to the issue of GOD by the end of the message.
The key point that I wanted to make is that mutations are simply random. They happen. They are not driven by outside forces or conditions. They are not directed, not from worse to better, from less to more or inferior to superior.
The difference comes with the filter.
And now back to the concept of God.
There are two issues there IMHO. First, GOD either exists or does not exist. If he exists, then he will exist regardless of what we believe.
The second part of the God issue relates to theology and religion. The existence of GOD and the existence of religion are two different questions. Why do we believe in dieties?
IMHO, the growth of religion is pretty simple. As others have mentioned, the world is full of many things we cannot explain. This was particularly true in the past, but still true today. In the past, many things were assigned to dieties. It was a way to explain the unexplainable.
As we learn more we assign less and less to dieties. That is a normal progression.
Yet it still has no relation to the existence or non-existence of GOD. GOD exists, or does not exist.
So religion, faith, becomes clearer, simpler, less confronted. Theology, religion, are a matter of belief. It is not science, not logic, not provable. It's faith.
But regardles, GOD exists, or does not exist. That is beyond our belief system.
