Yes, agree, it is the most sad moment but it is seems to be relatively realistic. I think we human often do not think about the consequences. I think if aliens try to do the experiments and will end up with the same result who knows what will be the outcome of their conclusion. For me, I think we need more “brain” and not to be selfish :)

Our mind likes to trick us and often we can catch us on some thoughts and often we do think is it real or is it imagination :)
