You're moving the goalposts, though, Khandro. The Cambrian Explosion -- which is the issue at the heart of this video -- has nothing to do with commencement of life, which happened some three billion years previously or even more. Your Intelligent Designer took an awful long time to get going, didn't he?
The crux of your argument seems to be that ID is somehow the mainstream theory and we're the ones challenging it, but this is just a not-so-subtle sleight of hand. You are the one, on Meyer's behalf, making the challenge to the mainstream and the onus is therefore rather more on you to put the case. You have, so far, not managed convincingly to do so. I don't have to explain why the mainstream is the mainstream, in excruciating detail, to attempt to deconstruct Meyer's arguments point-by-point. It seems to suffice to point out that you don't seem to understand what they are yourself, since you keep changing your mind about what part of the theory is in question.
