The similarity between xian belief and evolution are easy to see after the fact.
You could do the same with a virus: seeing xian thought as a virus that spreads via a host (and indead needs a host to carry on) would seem to cover all the bases.
I think if you look hard enough you can see anything in anything.
I remember hearing about a film once that cut from colour to black and white half way through: it was praised for it's avante guarde approach to film making and critics drew rich parallels with this and that only to find that the director ran out of cash and had to film in on cheaper b/w film.
The moral? We see what we want to see.
Science is not like that (or at least it has stringent checks that eventually weed out wishfull thinking).
