Last week the media was all abuzz about a story that a NASA scientist had discovered “definitive evidence” of alien life in a meteorite.  In fact, they apparently even had photos of the little critters…

NASA scientist finds evidence of alien life

Aliens exist, and we have proof.

That astonishingly awesome claim comes from Dr. Richard B. Hoover, an astrobiologist at NASA’s Marshall Space Flight Center, who says he has found conclusive evidence of alien life — fossils of bacteria found in an extremely rare class of meteorite called CI1 carbonaceous chondrites. (There are only nine such meteorites on planet Earth.) Hoover’s findings were published late Friday night in the Journal of Cosmology, a peer-reviewed scientific journal.

“I interpret it as indicating that life is more broadly distributed than restricted strictly to the planet earth,” Hoover, who has spent more than 10 years studying meteorites around the world, told in an interview. “This field of study has just barely been touched — because quite frankly, a great many scientist [sic] would say that this is impossible.” …

The “field of study” to which Dr. Hoover is referring is astrobiology, and it is a legitimate scientific endeavor that attempts to study the question of life beyond Earth.  Unfortunately, Dr. Hoover is somewhat of a crank, and his claims are quite overblown, as evidenced by the ruthless criticism he and the “peer-reviewed” Journal of Cosmology received from the wider scientific community.  Here are just a few samples of how these trumped up claims of “alien life” simply wither under scrutiny…
