> imagine the code arose originally by random chance
If you said this in any other context, it would sound laughably ludicrous. Imagine billions of lines of code for an incredibly advanced, complex and self-replicating system appearing out of the thin air (over 2 bil. yrs) by mere chance. Even with the long time period, it sounds facetious, prima facie. For some reason people decide to switch off their common sense and rationality when it comes to this.
