The fascinating thing about those primordial planets you encounter is how they're basically recreating the famous miller-urey setup in digital form (a groundbreaking experiment that showed how life's building blocks could form naturally). When you're exploring those atmospheres filled with methane and ammonia, especially during lightning storms, you're actually seeing the same conditions scientists used to demonstrate how amino acids might have first appeared.

What's really interesting is that these stark, lifeless worlds aren't just random designs – they're actually based on real scientific principles about how life might emerge (this is why you'll often spot volcanic activity or electrical storms in these areas). The whole setup mirrors what we think early earth might have looked like, and spotting these familiar conditions can give you a good hint about a planet's development stage.

Maybe worth noting that whenever you run into planets with thick atmospheres and lots of energy sources like lightning or volcanic activity, you're looking at exactly the kind of environment where organic molecules could theoretically start forming (these are usually great spots to look for rare resources, by the way). It's pretty clever how they've taken real scientific concepts and turned them into explorable environments that actually make sense from a chemistry standpoint.
