Nowhere in the text you posted is there ANY mention of evolution or evidence of evolution. The text is referring to the very beginnings of abiogenesis.
Maybe I'm missing something here, but in case it helps, abiogenesis deals with how the very first life may have arisen. Evolution deals with how this life then changed in response to various factors and doesn't even consider where it originally came from.
An analogy to what you seem to be saying is "I can't bake a cake because I don't personally know the chicken that laid the eggs I'll need". If I'm baking, I don't give a toss which particular chicken laid the eggs, I crack 'em into a bowl and get working.
