ET caught between rock and a hard space

COULD this be the real ET?
According to new reports from NASA, scientists have discovered tiny fossilised bacteria on three meteorites.
They believe that the microscopic life forms are not native to Earth -- in other words they are aliens.
According to researchers, this would suggest life in the universe is widespread and life on Earth may have come from elsewhere in the solar system.
The breakthrough seems to support theories that life may have come to earth by riding on space rocks like comets, moons and other astral bodies.
The study, published in 'The Journal of Cosmology', is considered so controversial it is accompanied by a statement from the journal's editor seeking other scientific comment.
The central claim of the study by astrobiologist Richard Hoover is that there is evidence of microfossils similar to cyanobacteria -- blue-green algae -- on the freshly fractured inner surfaces of three meteorites.
These microscopic structures had lots of carbon, a marker for Earth-type life, and almost no nitrogen, Mr Hoover said.
"We have known for a long time that there were very interesting biomarkers in carbonaceous meteorites and the detection of structures that are very similar. . . to known terrestrial cyanobacteria is interesting in that it indicates that life is not restricted to the planet Earth," Mr Hoover said.
Mr Hoover has specialised in the study of microscopic life forms that survive extreme environments.
