There are good reasons why life didn't form. Peptide and nucleotide bonds need to form from amino acids before proteins can form. This means the input of energy with the release of water....alternations of heating snd cooling, wetting and drying for chain length extensions. All this in the presence of both infrared and UV radiation. On Earth this took place protected by ozone derived from oxygen produced by stratospheric UV photodissociation of water with the loss of light hydrogen to space. None of that could take place on an asteroid.

Maybe we are not special. These building blocks are universal so that means life can form in other environments than ours. We can't expect duplicating results but why would we believe we were the only conscious intelligent beings?

Ask yourself.. what are aliens made of if they are different from us and how long did it take their evolution to get it done if the environment was different?

Seems to me life needs more than what was on Benny. That is why none formed. My question is why did the parts we found exist? How did they get there?
