Our next planet is Gliese we landed on it 3 days ago and launch robots to investigate area around our ship. Although our central computer didn't find any signs of life we still hope to find some creatures. After 2 days of searches we finally found it! It was huge monument and crystal inside it. Something was written on it. Our robots copied text and try to decipher it. But unfortunately they can't. So we send it to our central computer and it translated a headline. It goes:"O..R MESSAG..TO OTHER LIFE ..ORMS."
But it still can't translate whole text, so YOUR TASCK is to decipher the ancient text and send it to our central computer.
