The moral of 'the friendly alien story' is difficult to determine without knowing the story itself. However, it might carry a message about unity. In a scenario where an alien is friendly towards humans, it could imply that all beings, regardless of their origin, can co - exist peacefully. It could also suggest that we should look for common ground rather than differences. For example, if the alien has different values but still manages to be friendly, it shows that we can learn from each other and build a better relationship through understanding and cooperation.
I'm not sure as I don't know the details of the story, but it could be about acceptance and friendship across different species.
Since we don't really know the 'the friendly alien story', the moral could be related to open - mindedness. If the story is about humans and an alien becoming friends, it might teach us to be more accepting of the unknown and not to judge based on appearance. Maybe it also shows that kindness can bridge any gap, even between beings from different planets.
