Scientific American Life Is Complicated—Literally, Astrobiologists Say

     Today, I read an article about chemistry. It said that the hunt for extraterrestrial life is difficult. For example, it was believed that there was life on Mars.
     NASA stated that Mars had the possibility which exists extraterrestrials in 1970s, because there are radioactive carbon from Martian soil. However NASA finally admitted that the evidence was wrong.
     The debate whether there is an extraterrestrial life will continue forever.

  1. Wow, it's sad news. I'm one of the people who believed in extraterrestrial life on Mars.
    I want someone to end the debates.
