I did not know that the Americans were planning to send a probe to Europa. I would have suggested that they write "Mabuyani", meaning "Greetings" in Kalanga languguage, outside the probe. You see, Europa is best understood when said in Russian - Evropa. This is Kalanga language with Sumerian corruption. In Kalanga "Europa" is mispronunciation of "I-be-lopa", literally meaning "Those of blood"; that is "blood relatives." So the Titans are telling us that their brethren live on Jupiter's icy moon.
I sure hope to be still alive in 2030 when the probe arrives. If not, well, just too bad!
