Intelligent Design does fit with all the facts. But that's it's problem, it fits with anything. Whatever we find in the universe you can answer that the "intelligence" made it that way.
If lightning strikes you dead, God did it. If we find fossils in the ground, God put them there. If we found them this way, or that way, with this radiocarbon dating or that, then God did it that way, and we don't know any more than we started out with.
Intelligent Design is the anti-science. It implies that we can't discover anything, because the Intelligence can fool us, or change the facts at His whim. We can never be sure of anything under such a philosophy.
