I have often wondered why God created some of the Dinosaurs so large? When the fallen angels took wives for themselves, the result was nephalim or giants. Could this be because they were also much larger ? I think about the sin in the garden. Satan being the father of Cain , perhaps Cain was much larger than other people at that time. The Holy Spirit impregnated Mary. Perhaps the fallen angels interacted with humans in ways we do not understand. ???
