Well, OK, I probably came across as more dogmatic than I actually am.
There were two reasons for this;

(1) Roosen entirely ignored the issue of observational evidence, and made
some rather sneering insinuations which frankly got on my tits.

(2) I hadn't had my morning coffee yet.

If you're saying that big bang isn't in as strong a position as, say,
evolution then I agree with you. I'm well aware of just how far the
data goes, and of the problems that still exist. I'm also perfectly
happy (eager,even) to look at alternative cosmologies.

However I still stand by my use of "all", because I don't know of any
clear observational test which big bang has failed. If you can provide
an example I will, of course, eat my words.
