Even if they had a complete model of all of physics, it still wouldn't answer all questions, as a lot of important data is just random. Whether nature decided to go with D-molecule or L-molecule is essentially random.
iirc L-aminoacids and D-sugars, that is these observed in nature, are very slightly more stable than the opposite because of weak interaction
probably it's just down to a specific piece of quartz or soot that got lucky and chiral amplification gets you from there
also it's not physics, or more precisely it's a very physicy subbranch of chemistry, and it's done by chemists because physicists suck at doing chemistry for some reason (i've seen it firsthand)
