Good song, but I have to dispute some of your post.
Seems that there will always be individuals that want to believe in the ultimate supreme being that is responsible for the creation of our universe we are living in. Then there will be the Scientists and Ordinary individuals that see things and ask questions beyond what we know. Should everything be answered with "GOD made that" to subject that we do not know the answer to. I think not.
Actually, the answer to that question is 'yes'. As Aurino correctly pointed out recently (paraphrasing), answering even one question properly requires that you answer all questions. That is, the subject of causation within science is an unsolved problem since there is never one identifiable cause for a phenomena. What Newton answered, special relativity found problematic. What Einstein answered, quantum field theory has found problematic. The point isn't that we should invoke a reference to God in every problem, however we shouldn't dismiss this reference to some degree either.
As for needing a reason to belong in this universe, some people don't feel the need to have to belong to a certain religous group to feel at ease with the current state of the universe we are in.
But, as human beings we have to find meaning in our lives in order to feel at ease with our universe. The problem with being aware of our own future demise is that we are forced to face these issues and therefore religion becomes an attractive option for the clear majority of people. Even those who aren't religious most of the time will still identify themselves with certain religious beliefs which they take some significant amount of comfort for those times which they might depend.
So which brings us back to the original Topic of the Term WORD. It means what you want it to mean based on which religion you subscribe to or it means something else based on your personal interpretation.
The term 'Word' is meaningful to those of mostly Christian affiliation, and for those who take comfort in the message of Christianity, it isn't so much a matter of what they believe but the sense of meaning that they take away with those beliefs.
