We have had these types of anthropic universe arguments before, and I don't see this being settled anytime soon, unless we encounter an alien life form or something that dramatic.
Apparently, this physicists have been making the rounds giving talks on scientific evidence that points to a designer. Unfortunately, this claim is highly misleading. There are several issues that need to be clarified here:
1. These so-called evidence have many varying interpretations. In the hands of Stephen Hawking, he sees this as evidence that we do NOT need a designer for the universe to exist. So to claim it that they point to a designer is highly misleading, because obviously there are very smart people out there who think of the opposite.
2. Scientific evidence have varying degree of certainty. The evidence that Niobium undergoes a superconducting transition at 9.3 K is a lot more certain than many of the astrophysical parameters that we have gathered so far. It is just the nature of the study and the field.
3. It is also interesting to note that even if the claim is true, it has a significant conflict with many of the orthodox religious view of the origin of the universe, including the fact that it allows for significant time for speciation and evolution.
4. The argument that the universe has been fine-tuned for us to live in is very weak in my book. Who is there to say that if any of these parameters is different that a different type of universe couldn't appear and that different type of life forms would dominate? We are still at an infant knowledge as far as how different types of universes could form, which is one of the argument that Hawking used when he invoked the multiverse scenario. So unless that there is a convincing argument that our universe is the one and only universe that can exist, and nothing else can, then this argument falls very flat.
I find that this type of seminar can't be very productive unless there is a panel discussion presenting both sides. People who listened to this may not be aware of the holes in such arguments, and I would point out also to the any talk by those on the opposite side as well. It would have been better if they invited two scientists with opposing view, and they can show to the public how the same set of evidence leads to different conclusions. This is what happens when the full set of evidence to paint a clear picture isn't available.
