Mars Mystery
A stray rock fell to Earth 11.000 years ago, 17 million years after its liberation from the surface of Mars. Some scientists thought that the meteorite bore evidence of microbial life - extraterrestrial bacteria - on ancient Mars.
Critics said the evidence for life was only circumstantial. As long as alternate explanations exist, a claim to have found the first indication of life anywhere but on Earth should require more definitive proof.
