Are you suggesting that there is something sinister behind a shadow on Mars?

No, they didn't... And a microbe is a form of life.
"I found that the gas release was indeed rhythmic, with a period of precisely 24.66 hours, a Martian day," Miller said. This finding, along with other painstaking assessments about LR operations, the scientist feels that a Martian circadian rhythm in the experiment may constitute a biosignature - a sign of life.
"In conjunction with a great deal of other data from this experiment, such as the very large increase in gas immediately following nutrient injection, as well as a slow rise over the course of the entire experiment, suggest that the LR experiment was seeing biology," Miller said.
Miller said, however, that chemical interpretations of some of these data are possible, perhaps accounting for part of the LR rhythm.
"On the whole, a biological explanation seems more plausible. In all probability, Viking discovered life on Mars 25 years ago. The presence of a strong circadian rhythm in the LR experiment further suggests that circadian rhythmicity may be an excellent 'biosignature' of extraterrestrial life," Miller said.
