Imagine that aliens do exist and they came to our planet. They aren’t hostile at all – on the contrary, they want to blend in and live like other earthlings. The problem is that they don’t know anything about how our world works. The laws of Earth physics are still a mystery to them, so they constantly risk their lives in the most ridiculous situations. You have to watch out for them and make sure none of them dies while making coffee, for example, or taking out the trash!
