On Titan the molecules that have been raining down like manna from heaven for the last 4 billion years might still be there largely unaltered deep-frozen awaiting the chemists from Earth

Summary

This quote highlights the possibility of finding preserved molecules on Titan, one of Saturn's moons. Over billions of years, molecules have been continuously "raining down" on Titan's surface. The quote suggests that these molecules could still exist in their original form, preserved due to the freezing conditions on the moon. Furthermore, it implies that future chemists from Earth may have the opportunity to study and analyze these untouched molecules to gain insights into the moon's composition and potentially uncover valuable scientific discoveries.
