Yes, I agree.
Both systems are logically consistent so there would need to be other reasons to choose one or the other.
If there is an (E) the only possible way we would have of knowing - would be if (E) communicated somehow and provided evidence.
Even if one considered complexity as evidence it would not be sufficient or specific about (E).
In my case, the evidence that leads me to conclude that (E) does exist has little to do with the complexity of life.
Anyway, thanks for your time and thoughts. I especially appreciate your insight about the requirement of eternal complexity in my point of view. That will give me something to think about for quite a while to ponder it's implications.
In the same my statement, "god's existence begs the question, who made him?" is not valid to you your question who made matter is not valid to me. The question implies creation and both of us believes that something wasn't created. We just differ on what thing is.
