Ogg, it is much better than a guestimation, we know what comets are made of, don't you remember those missions? We know what planetary disks are made of, we can see them.
They probably just used the surface of the container that they sublimated the ices in and scraped it off.
We could also identify pentoses, just not specific ones when they're mixed together with dozens of similar molecules, that's why we needed a newly developed process to separate them
That there is a universal presence of the "building blocks of life" is unsurprisingly lawful. The issue of the qualitative divide between the living and the inorganic remains.
No surprise there, nor is it very relevant to modern theories of life emergence that relies on local geology. Oh, well.
@tgbe: Modern theories of life emergence shows the reverse, there is no qualitative difference as the process happens, same as there is no qualitative difference when speciation happens. The difference in results is a separation along gradients.
Now, there is no useful definition of life that relies on qualitative differences. The NASA definition of life that tries to identify living individuals as opposed to evolutionary populations can be applied to evolutionary computation as well as to biological entities.
There is no mystery or difficulty here, but the continuation of biochemical processes.
