Evolution, with tons of facts and over a century of scientific research, with gaps pieced together with scholarly speculation, and every new piece of discovered information predictably filling one of those gaps vs. ID with no science and pure speculation based on blind faith in a few bronze age scrolls (while ignoring tons of other bronze age creation writings) and a lot of superstition.
ID is actually based on lots of observable evidence and facts. The main argument for intelligent design is based on scientific observation. The conclusion of IDers is, that after observing the facts, evolution does not and cannot reasonably account for life as it currently exists; including specific parts of the bodies of various non-plant life forms.
