I meet Ω∆˚¬†¨ˆø桧

            I was sitting in my house when suddenly a green thing walked in. I asked this alien what it's name was and it said something I couldn't understand. I asked the alien to write it's name down. This is what was on the paper "Ω∆˚¬†¨ˆø桧". I was surprised by 2 things. First, Ω∆˚¬†¨ˆø桧 wrote in green but had given Ω∆˚¬†¨ˆø桧 a black pen. Second, all of the characters in Ω∆˚¬†¨ˆø桧's name are from Earth. I asked where Ω∆˚¬†¨ˆø桧 found these characters. He told me that on his planet, ℜ¤❧∴, they invented these characters and many more. So this alien is telling me they invented Latin, Greek, and other Earthly characters? Ω∆˚¬†¨ˆø桧 asked if I have had ice cream. Ok so now the things on ℜ¤❧∴ invented ice cream too? I had some ice cream so I asked Ω∆˚¬†¨ˆø桧 what flavor he wanted. Ω∆˚¬†¨ˆø桧 said mint chocolate chip, so I gave him all I had. Finally Ω∆˚¬†¨ˆø桧 explained, once the inhabitants of  ℜ¤❧∴ had ruled the Earth but they left because they didn't like how little water we had here compared to other planets they had seen. They left behind tons of language and other ideas here for us to use.  How many things did they create that we use? After he finished his ice cream, he left in a space shuttle just like the ones we have.
