Basically instead of being what we would call wet nanotechnology which is what our biology could be described as, imagine if you will, organisms that evolved from 'dry nanotechnology' who are native to the void of space.
My idea being they evolved in an environment similar to Earth's moon.
The reasons why life evolved from water makes sense. Water is an amazing solvent and a medium by which elements are brewed and mixed together in a soup. Ammonia is also apparently another candidate, though it may have its issues.
However I wanted to know specifically if there's anyway such a form of life could evolve and maintain itself naturally with minimum intervention.
