Wrong at every fucking turn.
"no matter which way you slice it you can't explain nature with nature"
Why not? We can explain LOTS of shit in nature with nature. Just because we haven't gotten The Big Questions all answered to your satisfaction yet doesn't mean it can't or won't be done. There is no logical reason why we can't explain the cause of the Big Bang. We already have several hypotheses, but we can't test them yet. The LHC is actually going to answer a lot of questions in that regard.
"Considering the information behind nature's properties"
This thought is meaningless. What the fuck are you trying to say?
"and the fact that life is made up of nano-machinery"
So... your argument is that the fact that large systems are made up of smaller systems is somehow proof of a designer? Bullshit. That's a logical fallacy.
"and a brilliant (perhaps even optimal) genetic code"
Ditto my last comment, except this quote betrays your, frankly, appalling ignorance. DNA is neither brilliant nor optimal. It is ridiculously error-prone, clumsy, and most of it is "junk"-- that is, completely useless, ancient and depreciated, or duplicates of other pieces which are never used, among other shit. Humans have already developed far more intelligent and optimal systems for storing data. Your computer is proof. We're even experimenting with numerous types of artificial "DNA".
EDIT:
"Therefor my probability of God's existence would be very close to 1:1."
And where the fuck did that number come from, might I ask? How was that calculated, exactly? Oh, right, you pulled it out your ass. Well, by my calculations, the Christian God is impossible. If you'd like, I can go into a multi-page rant about how it makes no rational sense whatsoever.
