I do know Draconians are from another world and some Reptilians could be early Earth type humanoid creatures who evolved from the dinosaurs.
They have recently found out many things about dinosaurs not known 30 years ago such as the possibility they were warm blooded and they were also quite intelligent. The image of the slow and dimwitted creatures is left to shows like the original Land of the Lost.
I do think there are Reptilian creatures out there as there are many credible sightings and encounters. I also think we are being visited by Draconians as well as other types of creatures. But are they part of a plot to rule the world? If so, they would be doing so by now.
