As the number of unexplained, irreducibly complex biological systems increases, our confidence that Darwin’s criterion of failure has been met skyroc… - Michael Behe

... 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 reason to doubt it. ... I think that evolutionary biologists have contributed enormously to our understanding of the world. Although Darwin's mechanism - natural selection working on variation - might explain many things, however, I do not believe it explains molecular life.

In private many scientists admit that science has no explanation for the beginning of life. . . . Darwin never imagined the exquisitely profound complexity that exists even at the most basic levels of life.

If a theory claims to be able to explain some phenomenon, but does not generate even an attempt at an explanation, then it should be banished.
