''Just because you can ask something doesn't mean it has an answer. Reality is the way it is. Why it is this way is something that we may never know, because there may not be an answer.''

Right, there may not be an answer or the answer to the question "Why these equations and not others" is "It's random". Statistically, this isn't very likely, as it's far easier to construct an universe which cannot support life than an universe which can support life. ''We can only say that if the physical constants we know were different, then the universe would be different. To say anything else with certainty would require a level of knowledge and predictive ability we do not possess.''

What I said: If you would increase the Gravitational constant just a bit, there would be no life in the universe (Or at least a very different form of life)

''Also, what you're saying about physical constants is patently false. I've already pointed out extremophiles, which live in conditions unsuitable for most other life forms we know of, but the fact is, we only have knowledge of the type of life forms we've encountered here on Earth. ''

This has nothing to do with physical constants. Our universe allows this life forms to exist, or better: Life could develop under those extreme circumstances. You are confusing extreme conditions with different constants of nature, these are two very different things. But the basical constants of nature are still the same under extreme conditions. See Biology is just applied chemistry which by itself is quantum mechanics on the outter electrons of atoms.
