do you not understand. There is, oddly enough, no law of physics or rationality to prevent one from speculation, providing you start with a disclaimer such as "The origin of life remains very much a mystery".
I was not saying that evolution is invalid because evolutionists don't know what the exact origin of life was; Holding them to be in intellectual error because they don't claim to know it all is silly. I am saying that evolutionists like Mr. Rennie tend to gas on for whole pages at a time about how life could have arisen from non-living matter, but then claim that evolution has nothing to do with the origin of life, especially not the origin of life from non-living matter. That's like saying that creationism has nothing to do with belief in God, or that Intelligent Design theory has nothing to do with the concept of irreducible complexity.
