[meteorite-list] Can Microbes Survive a Million-Year Space Journey? Experts Say Yes

[Steve Dunklee]

if we found an earth like rock with life in it we would naturally assume it came from earth. and being an earth like rock it would be discounted as ever being a meteorite. i9f meteorites have arrived here from mars then earth meteorites with life in them mmay have fallen on mars.
cheers
