Two things:
Silicon does not work like carbon. It is a metalloid whereas carbon is not. It does not form the right compounds to form life (having lower electronegativity and there fore being likely to form ionic compounds) and isn't quite common enough. It doesn't form any gases, as this is physically impossible at temperatures complex molecules would be stable at. Also, a creature able to reproduce without genetic material would not prove god exists. The creature itself could be a giant self-replicating molecule itself. Difficult and outrageously complex, but hypothetically possible to engineer. Sure, a god might do that, but I think he'd restrict it to the same laws of physics and chemistry that everything else he made would have to follow.
Second, I don't see why the existence of a data sheet like that would convince anyone one way or the other. It could hypothetically be done with sufficiently advanced technology, it could be done by a god, or with a simple picture demonstrating an idea, whatever. You would have to have the same inverted sense of what is amazing that most of the human race does for that to convince you. It wouldn't be your fault, as that is perfectly normal human thought. Takes a lot to overcome without help. The fact we exist is freakin' amazing, but that doesn't say one way or the other whether any sort of god exists. However, it's good enough for me. I mean, we've got an entire universe made of these tiny little particles, which are each only composed of two or three base components. These particles are made of simple pieces and are extraordinarily complex, yet there are enough of them to make everything, and the interactions between the different particles made of those simple base components, which further break down into at least six other components, are what all of our laws of physics and chemistry are determined by. In short, our universe is one giant, complex machine made of only six repeating parts which will only come together in groups of three, making the things that compose atoms. Blows my mind every time I think about it.
