I think Stephen's new approach is better, in which he simply asks whether it's worth worshipping God, rather than trying to address whether God exists at all. The former question is far more straightforward, independent of the ambiguity of the term "God", and thus amenable to empirical assessment, imho: clearly, it really isn't terribly important to worship him, because it makes no tangible difference to the lives of people whether they do or do not.Whether it's worth worshipping depends on what you mean by "God" and what you mean by "worship".
If by worship you mean "assign ultimate worth to" (as opposed to the opposite end of the worship spectrum, "abase yourself before") then worship is something we all do when we decide on our values. We do it when we fall in love, stand enraptured before the beauty of Nature or are awed by the exciting knowledge about to be revealed by the Large Hadron Collider.
If by "God" (I prefer the gender-neutral term "Divine") you mean the wonder and mystery of being alive, the beauty of the white Moon among the stars, the magnificence of galaxies, and the beauty of Nature, then yes, it's worth worshipping (in the sense of assigning ultimate worth to). It's also worth communing with, meditating on, writing poetry about, and exploring empirically. But is there any point trying to reclaim the words "god" or "divine" to mean all that? Not, in my opinion, if you mean something supernatural, ontologically transcendent, and of pure essence. I think the term Tao describes it much better; it means the way, and thus implies constant movement and change, and it is immanent in the universe, or even an emergent property of it. If the divine/deities/genii loci is/are (as I propose) the emergent consciousness of complex systems, why shouldn't the Universe have consciousness? (Teehee, I said this to a major proponent of emergent complexity; I think he was a bit horrified that I was using his theory like that - but I reminded him that I was only proposing a hypothesis, at which he was somewhat mollified.) There's no particular reason why walking bags mostly made of water suspended from a calciferous internal structure should have consciousness, so why not other complex systems?
If by "God" you mean the alleged authoritarian in the sky with the big stick, then the answer is definitely no, especially if the worship is of the self-abasement variety.
