"... does that mean the more complex a piece of music, the less likely it had a composer? etc. etc. etc."

of course not! But the issues are not comparable. We KNOW (as well as we can know anything) that music HAS composers. We SEE composers...we have pictures of them...we interview them...etc...

Your example breaks one of the rules (called 'informal fallacies')..You have equated two things that do not really share the same attributes....a piece of music and the universe.

It is...literally...impossible to stand outside the universe and examine its creation. We can sit in a room and watch a composer scribble and play notes.

That's why I say that is is just as easy for me to NOT imagine an 'author' of the universe as it is for you to imagine one.

Basically, I am staying neutral...I simply do not know. I wasn't there...no one was. I am not making a claim.....I am saying I do not accept YOURS! It is interesting to STUDY the universe and see what we can find out, and I am happy with that.
