自古以来,寂寞孤独的地球人一直在眼睁睁地仰望苍穹,试图在茫茫太空中寻找到自己的同类,也寻找到自己的根。即使到了今天,地球人也仍然在既不知道时间地点,也不知道频道频率的情况下,企图去读懂想象中的外星人所发来的“天书”。对于寻找外星文明,有人满怀希望、信心百倍,但更有人沮丧失望、长吁短叹:我们是孤独的! 在拥有数以千亿计恒星的银河系里,难道就只有孤零零的地球人? Since ancient times, the lonely and lonely earth people have been watching the sky, trying to find their own kind in the vast space, but also find their own roots. Even today, people in the world are still attempting to read the “book of al-days” sent out from the imaginary aliens without knowing the time and location or the frequency of the channel. Some people are full of hope and confidence in their search for extraterrestrial civilization, but some are even more disappointed and frustrated. They are sighing alone: ​​we are lonely! Is there only solitary Earth people in the galaxy with hundreds of billions of stars?
