46、s before and whose body had never been foundThe scientists who rushed to look at the body thought it was probably much older，maybe even a thousand years old With modem dating techniques，the scientists soon learned that the iceman was about 5，300 years oldBorn in about 3300 BC，he lived during the Bro
