I think you completely missed his point (or I am missing it and yours, too ;)).
I didn't see him saying a God is a more believable solution to our problems and questions. I also didn't see him state that scientists have not admitted they were wrong.
All he said was that many people treat science with the same dogmatic fervour others treat their deities with.
And on that count, he's absolutely right.
If you say that religious writings must be questioned because they have been created by humans, then questioning scientific studies must be allowed just as much, because they are human creations as well that can be influenced by other factors than merely wanting to find 'the truth'. Something they just want to find a very specific truth. One must remain wary of that.
On that note, intelligent design, in a true scientists eye, will hold the same merit as the theory of evolution until one of the two is supported by facts and a deeper understanding of the world. Both could, essentially, have a lot of support going, one could pull ahead only to be overtaken by the other again.
The point of science is to NEVER say "Well, we know enough now to not have to question it anymore, AT ALL!"
Sure, you can rest comfortably in the assumption that, with all the evidence, you're probably on the right track, but you simply MUST keep an open mind for new facts and arguments. THAT is science.
