All true, which means "chance" can't be the explanation; on that, all sides are agreed.
Of course, the odds against Avogadro's number of sodium chloride molecules "just happening" to arrange itself into a cubic crystal are also so astronomically huge as to make the event a practical impossibility.
The conclusion we draw there is that some sort of physical law is at work -- a conclusion that would be justified even if we couldn't yet state the law precisely, as long as there was no compelling reason to the contrary.
What we need from the ID crowd, and haven't seen (and in my opinion aren't going to see), is just such a compelling reason to the contrary.
Something not mentioned very often is that DNA readily takes a crystaline form. I can't help thinking this will eventually have some relevance to calculating the odds.
