Science and the existence of god 

Now that I have the annoyances out of the way, back to the good stuff :) George Johnson asks whether science can prove the existence of god.

God, for those who want to use that term, can be invoked to account for phenomena that have not yet yielded to the scientific method. What is for some the ultimate question — Does God exist? — has become a matter of how much further the domain of the unknown will continue to contract, and if it will ultimately evaporate. The momentum has been in that direction. The whirlpool of cosmic stuff that spawned the solar system spins because it is one small part of the great rotating galaxy, the Milky Way. When a random fluctuation causes enough gas and dust to bunch together, gravity takes over and celestial bodies begin to form. If you want to know where the galaxies came from, there are answers as well. Ultimately, it all comes down to the Big Bang.

That is where the chain of reasoning bottoms out. What caused the primordial explosion? At this point all but a few scientists go with Wittgenstein ("of what we cannot speak we must pass over in silence") or with Kierkegaard, blindly taking the leap of faith into the abyss of the unknown, choosing what to believe.

Why there is something instead of nothing is not an issue that science is well equipped to address. As cosmologists understand it, the primordial eruption did not take place at a certain instant in a certain place. The Big Bang created absolutely everything, including space-time itself. How can anyone ask what set the whole thing going if there was no space or time for a creator to be in, much less any matter or energy for Him or Her or It to work with?


I am not sure why science is required to prove the existence of god. The current inexplicability of the Big Bang is just as true for god. So why not use Occam's Razor instead?
