Divine will takes its place in a row of many other theories of creation of the Universe. If you're going to stick to scientific approach you won't go any further because I don't think we will even find out 'the truth'.
Well, gravity is a consequence rather than the cause of either spontaneous or deliberate 'tuning up of the Universe'.Gravity is there, it works, it's not random at all but not the product of a will either (unless by extension you make it part of the Big Bold Concept underlying the universe, which then would make everything including other religions and atheists the product of the selfsame will).
I noticed some tendency when 'openminded' people bash the followers of the 'divine theory' denying even the possibility of it being true (well, why not until proven otherwise at least) and at the same time listen to pure gibberish of some raving lunatic pretending to be a scietist. All theories then should be considered with equal scepticizm (at least).
