What's wrong with leaving it as "inexplicable"? Are you going to be so arrogant as to say that, in our short time of infesting this planet, we have managed to uncover all the secrets of this universe? We don't even know much about how our brain functions, about how the forces of the Earth work in harmony with eachother, why some people act how they act..... if and when we finally manage to begin exploring the outer reaches of our galaxy there are going to be even more unanswerable questions. Science is an ever-evolving entity, and every answer raises a load more questions which, in time, we discover the answers to, and so on and so forth. Modern religion sees this, and evolves with it. For every scientific discovery we find, you change your theories to suit your beliefs. You'll say "science can't prove x, therefore God exists" and when x is proven, you'll say "well science can't prove y, therefore God exists".

Don't pretend that God is the only alternative to what we don't know. The only thing God is an alternative to is logic.
