Yet, you would think that to prove one system arose from nothing but random chemicals, then transformed itself to something else, one ought to have something a little better than the catch all, murky process, "why, it evolved!"
This is the central point the ID side keeps making--show us how it happened, or even could have happened! Don't just rely on this mysterious "it evolved." Don't just say that someday we'll know how it evolved. At some point, for skeptical people to believe the process of evolution happened in the past and accounts for all life forms ever on the planet, somebody, some time, is going to have to actually demonstrate it.
