Then, Larry Krauss responds.
The original piece was an article by Larry Krauss, “Cosmology Without Design”:
To assume that the universe is fine-tuned for life because we exist in a universe in which we can exist—this is a little like a single individual, alone in the world, looking down at his legs and finding that they are remarkably fine-tuned to touch the ground. A millimeter shorter and they wouldn’t make it. A millimeter longer and they would be buried underground. Thanks to gravity, no such fine-tuning is required. In a cosmic sense, we are like the isolated individual. We simply do not know enough to ascribe significance to things that may be accidental, or that may be governed by some underlying principle, like the existence of gravity.

Steve Meyer offered a
rebuttal:
Cosmological fine-tuning exemplifies just the kind of evidence we would expect to find if a purposeful and intelligent agent had acted in the past to design the universe as a fit habitat for life. It does not seem to be the kind of evidence that one would expect if the universe had arisen from “blind, pitiless indifference.” Nor do Professor Krauss’s arguments alter this probability calculus.

Oh, and Larry Krauss replies:
If, as Meyer seems to require, life must be like the life we experience on earth, presumably designed in the image of God, then the Universe is a horribly poor environment. In almost every other location we see in the Universe, life like our own cannot arise. Indeed, even here, our survival involves a constant battle against a harsh and seemingly indifferent universe that is trying to kill us, as it eventually will. But why must life be like our own? Meyer argues, without any underlying evidence, that life has to exist on rocky planets like our own. But some, like my late colleague Freeman Dyson, argued cogently that in the long run, other sorts of intelligent life could arise even in the very “diffuse clouds of hydrogen” that Meyer finds so inhospitable—the black clouds of Fred Hoyle. The rules for such life-forms would undoubtedly be very different than for us.

We await Meyer’s reply… he won’t disappoint us.
