I looked at the first link and skim-read it.
It appears to just be saying that because molecules bond in a certain pattern it must of been intelligent design, and that water is complex yet a simple product when alone.
I will give you an example. Say, you meet a girl (assuming you're a boy), and the chemistry between you two hits off just great, you form a
bond with each other. Now, you perceive yourself as in love, as do millions and millions of other people on the world. Are you going to say, that God creates this pattern each time and not allowing the chemicals and nervous system to formulate its own reactions?
You will say, that the two are not alike at all, but all cells have a nucleus, which have the programming of the cell's commands. Which is why, many viruses seek the nucleus to "override" it and corrupt some of its data, just like how a computer virus would. That is why often you see "un-natural" formations in cell structure, ie. mutations, extremely fast growth in a plant, etc, because something entered the nucleus and changed data around. Everything started at the original product, and went from there.
Water is a complex system inside cells because of the acids it combines with. While when the water is taken OUT of the cell, it is pure H2O, when in it forms nicely into the cell's system. That is why extreme amounts of pure water trying to come in, can possibly kill the cell or overload the network. The cell requires a certain amount of water to operate, and it can bloat a bit as well, but there's always the saying that,
Too much of a good thing is a bad thing.
