Well truthfully, I always took Older than souls, to mean older than human and monster souls, as that is what the leviathans are, also souls between humans and monsters aren't that much a like, in humans the soul seems to provide morals and ethics, while monsters aren't bound by any, also Benny's soul, that we saw a few episodes ago, looks next to nothing compared to all the human soul we've seen (in Something Wicked, Long Disatance Call, My Bloody Valantine, Appointment in Samarrah) human souls are all a light blue/ grey colour, and are like energy, while monster souls are orangy red, and are like a hybrid of energy and liquid. So its safe to assume a Leviathans soul is nothing like either's.
