Earthling or not?

Live bacteria have been found inside a meteorite in the Naples museum, Italy. Two researchers at the University of Naples claim the bacteria are not from Earth. If this is proved true , it could dramatically settle the controversial theory that life colonised Earth from space. But UK-based geologists, who found bacteria living inside a meteorite in Antarctica last year, caution that researchers may ave misinterpreted the evidence. The proof that the bacteria were not terrestrial, researchers claim, is that they survived when the sample was sterilised at very high temperature and washed with alcohol.
