Aliens are dicks:
"We were extremely excited to have made contact with this highly advanced form of life, but it quickly became clear they’re pretty big jerks," said NASA scientist Raymond Morrison, referring frequently to a 24-page transcript of the interstellar transmission filled with patronizing language and backhanded compliments. "After telling us they hadn’t exactly been holding their breath waiting for us to figure out how to make contact with our ‘charmingly simplistic devices,’ they informed us they had studied our planet millennia ago but decided it was ‘too hopelessly primitive to be worthwhile.’"
According to NASA, the alien species described Earth’s 78-percent nitrogen atmosphere as a “decent start,” and said mankind had “come a long way in the past century, relatively speaking, considering it took [humans] a full 4 million years to walk upright.”
Actually, never mind. Maybe they’re right - we are quite primitive to each other.
