There are so many things were already able to explain , but what about the percent that cannot be explained ? .......I'd say we should all believe that there is something more out there , something not human but possibly related to our ancestry , whether your against what I think or with it , it can never change my belief that there is a higher intelligence that we ourselves are yet to understand , one day hopefully , we will all understand that we are not alone , and maybe if there's a chance , maybe they will spare us , and not do the things they do in the movies , that's all I have to say , ag 1 for lights , throttle for takeoff , pitch to tilt forward and backward , roll to tilt its sides , yaw to rotate in circular motion .
