Well, no . . . to be concise.
Here's a thought experiment or two:
If we use a simple ratio, comparing the amount of physical space that supports human life to the amount of space in the universe that probably doesn't support human life, what percentage of the universe would you calculate that supports human life?
Considering that the universe is still expanding, that number may be so small, and getting smaller. . . Maybe even approaching zero. A nearly zero percent proportion of space that supports human life.
We could also use statistics. Let's say aliens from another dimension decided to take random scoops of space from our universe, and sift through it to look for signs of intelligent life. They scoop sections the size of our solar system a thousand times in random coordinates around the universe.
Based on our limited knowledge, there is a good chance that they will find zero signs of life in their 1000 random samples, and statistically conclude our universe doesn't support life at all.
Obviously, these are only thought experiements . . . and there is no current way to know that any of those assumptions are actually true. . . But intuitively it feels right to say that based on our current knowledge, almost the entire universe is probably incredibly hostile to human life. Heck, most of our own planet's surface is incredibly hostile to human life.
So when I see the links you posted, explain how amazingly fine-tuned the universe is, I think of these thought experiments.
If the universe were designed for life, it was very poorly done. And because (back to our original topic) we only have a single instance of this, it is impossible to know what changes specific variables would ultimately produce.
Perhaps the entire universe would be teeming with a multitude of intelligent life forms swimming in a universe sized bath of self-sustaining nutrients. . . Vast civilizations teeming with alien civilizations in intergalactic warfare? Absolutely nothing? Who could say?
But looking at the probability of the variables that produce humans on planet earth is a terrible way to go about statistical inference or design arguments.
Again, I hate repeating myself here, but we only have a single instance of a universe, and we are stuck inside it. There is no way to claim that the variables that "support life" in our universe is improbable or impossible, because there are no better or worse examples to compare it to.
But even if I were to grant evidence of design, we'd have to conclude, based on the evidence we have so far, that it was so poorly executed it may as well have been accidental anyway.
