Reasoning is essential in science and in cryptozoology. But how do live pterosaurs relate to the Bible or to reasonable application of Biblical scriptures? Each individual has special spiritual needs, notwithstanding the critical similarities in need that each of us possesses. Some individuals spiritually need what reports of live pterosaurs provide.
The Old Testament mentions several strange animals, creatures not easily reconciled with modern knowledge of standard classified organisms of zoology. Two of those are named “fiery flying serpent” and “dragon.” Could some of those references relate to the same animal, namely Rhamphorhynchoid pterosaurs? I believe so. But much about this has been covered elsewhere; I will not be redundant here.
Modern living pterosaurs give credence to Biblical scriptures referring to the fiery flying serpent, and possibly to some references to dragons. They make sense of those Bible scriptures, making it more-easily understandable to hold onto those ancient principles that actually do apply to our modern lives.
