In 1978 NASA sent a rocket to explore Jupiter and they discovered that there were aliens living there. The aliens were full of frustration when they discovered them because they thought they wanted to take over Jupiter so they sent a threatening message. NASA received it and were scared so they sent a reply explaining they just wanted to be friends. The king of the aliens accepted their friend request and they started talking about their differences. When asked: “Do you like butter?”, “no” he said, I like marmite“. 10 years after that they ended up sharing planets.
