If Alians saw WW1and WW2 and what we are capable of doing each other then they'll, be clever enough to pass on the some other way of universe bcz it is big enough. And amazing that we can destroy ourselves 8000us +9500russ+500others, atomic warheads, Lex, how much time we can destroy Earth? And it is funny that some trigers are on auto mode, AI from 70 iest- so called'death hand'. Why we need Alians in the story.
