As the number of unexplained, irreducibly complex biological systems increases, our confidence that Darwin's criterion of failure has been met skyrockets toward the maximum that science allows.

We are not inferring design to account for a black box, but to account for an open box.

It is often said that science must avoid any conclusions which smack of the supernatural.

The theory of undirected evolution is already dead, but the work of science continues.

As commonly understood, creationism involves belief in an earth formed only about ten thousand years ago, an interpretation of the Bible that is still very popular. For the record, I have no reason to doubt that the universe is the billions of years old that physicists say it is. Further, I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it.

Despite some remaining puzzles, there's no reason to doubt that Darwin had this point right, that all creatures on earth are biological relatives

Science is not a game in which arbitrary rules are used to decide what explanations are to be permitted.
