This is merely wishful thinking on the part of those who want to just toss out any olld explanation and make it stick.
Tell me, did you fall for it?
Because you are essentially saying that the "god did it" explanation should suffice and should not be questioned.
If we followed this 'explanations need no explanations' idea you are touting, we would still believe that the earth was flat, that men deposit a seed into the incubator women, that the sun revolves around the earth, etc.
I mean, seeing as the explanations above (all of which are FALSE) would not need any explanations....
erm no in fact we believe in anything is because of this, ok ill try and write it out for you.
say that I found some arrow heads and axes in an excavation and said hey there must have been humans here at some point.
now from what Dawkins is saying it just isnt enough to make that statement, with that evidence, you must first prove the explanation that they are in fact arrow and Axe heads, then you must explain that explanation, and so on, to teh point were you would never be able to use the explanation that there were humans there in the first place.
The same is with such things as the Kalam Cosmilogical Arguements if God is the best explanation of Cosmilogical events then we can accept it without explaning it, until of course better evidence comes along that disproves God.
(im not arguing the kalam just using it as an example, this is the kind of arguement Dawkins was attacking when he made that statement)
