IMHO, fans of intelligent design seem to assume that what is mysterious today will always be so, and that we are better off invoking a supernatural explanation. This is defeatist, and no better for religion than for science. Basing a spiritual faith on the inadequacies of present-day science leaves believers with nothing more than a God of the Gaps, and even if those gaps are never eradicated, science will continue to close old ones and open new ones. Follow this path and you have a nomadic designer armed with suspiciously shifting powers of influence, almost a trickster of sorts. Personally, I don't believe that's what God is all about.
Almost true. Fans of intelligent design seem to assume that what is mysterious to them today will always be so. In this case, they're correct.
