There was a comment below this clip on YouTube that I thought was very thought-provoking. It said:
"The reptilian theory is outlandish, but not as impossible as you may think. If the dinosaurs weren't wiped out, the dominant evolved species on this planet would be.....reptilian humanoids! Insect humanoids is even possible. Also, some animals have the ability to change their appearance according to their surroundings, lizards, moths, octopus, etc. I'm not saying any of this stuff is true, but in theory it IS possible, and if it is possible, then you can't discount it."With that said, I'd like to add this. God did wipe out all life on the surface of the Earth during the flood. What remained was sea life, including reptiles. If the fallen angels returned after the flood and abducted humans (by way of UFOs), which in turn did genetic engineering with abducted reptiles - perhaps this is possible.
Or, you can throw out the whole theory and consider that the original 13 families made a pact with the devil. Who truly knows for sure!
