PLEASE ANSWER!!!!!!!!!!!!!!!!!!!!!!!!…

Ok. Is there bacteria/microbes out of the earth's atmosphere? If there is then that means there are life out of the earth's atmosphere? And can people who would just live on the moon, would they die or get sick? (IF THEY DO GET SICK AND GET OLD MEANS THAT THERE ARE LIFE OUT OF THE EARTH'S ATMOSPHERE RIGHT?) So, astronauts which have been out of the earth's atmosphere has brought bacteria/microbes to outer space and to the moon right? So please answer my question. Thanks in advance.
