Ever notice that reptiles are a rare breed as a species in that they are one of the few species that NEVER stop growing throughout their entire lifespan? According to the Scripture they also did not eat meat in the beginning but rather the green herbs and plants. Suppose for a moment the possibility of an evil fallen race of angelic-spirit beings coming down to earth and altering the genetic code of the living creation of YHWH 'Elohiym until they finally discovered that reptiles never stop growing? or that perhaps even their own alterations caused this anomaly? They apparently altered reptiles for their own purposes: to feed their own Titan-Giant offspring which 1-Enoch states that they had hoped would live five hundred years or more. Apparently one of the adverse side affects of the genetic manipulation was that some of the reptiles like T-Rex also began eating flesh instead of herbs.
