Paal saying "Down here I'm mortal" pretty much means that their civilization advenced SO MUCH that Immortality is a real thing, and technology is most likely the leading cause of it. Where they were stranded, there were no Technical advences other than what they had on them, so they didn't have what they had back on their planet, and their lifespan drastically shortened, effectively maing them "Mortal".
