I'd recognise that voice anywhere, it's good to see the Dimond brothers are branching off into other fields.
In all seriousness though, it's a good video and well worth a watch(although it's a shame they got the brother with the more monotonous voice to narrate it). He makes a couple of mistakes early on though, such as assuming the age of the galaxy can be accurately calculated by just dividing the number of supernovas total by the number per year. That'd be the equivalent of going around counting corpses in a graveyard and dividing it by the number of people who die per year to get how long a town has been around. The town didn't spring into existence the moment the first of those deceased died for one, as he'd have lived there his whole life before that. And for second, corpses older than a certain point might have rotted away to the point where we can't find a trace. Besides the whole age of the galaxy thing, an atheist would call all his arguments about how our solar system and our Sun had to be just perfect, as they'd say life could exist in any solar system and that it's just a game of chance(the arguments about the improbability of life in the Universe, due to all the forces, etc. still stand though of course).
Nevertheless good points are made. I found another docuмentary once years ago when I was going through a period of doubt which was very well produced and convincing, without a flaw. I'll try find it again.
