Asteroids May Have Brought Sugar to Earth

There seems to be a step missing

I don't understand how the presence of sugars in asteroids suggests that meteors planted sugars on Earth. If sugars can be created through inorganic processes, where's the argument that such processes were not responsible for the sugars on Earth? If they cannot be so created, then sugars are not the seeds required for life, and so there is no reason to suspect that life was seeded by meteors. I don't find the discussion at the end of the article particularly helpful in this regard.
