Right around now would be a good time to start. List (with qualification by other scientist) why you disagree with the conclusions of the specialist
contracted by NASA....
I already provided two simple experiments that don't imply life at all...yet if you analyse the data you can find a strong circadian rythm.
You suggested filling glasses with water which is has nothing to do with the process followed by the LR experiment.
For your information, circadian rythm means that the processe you're observing has a cyclic behaviour with the same period as the earth
rotation (or Mars in this case), that is a daily variation...so if you measure the tempretature during a day you'll get a circadian rythm.
It could be something else, running out of options thought, but if one adds up all the other facts that point strongly to life you will also come to
see that it's life we are looking at.
And like I said...a circadian rythm is not a sign of life
More specifically, says Miller, the fluctuations in gas emissions seem to be entrained to a 2 degrees C fluctuation inside the lander, which in
turn reflected not-quite-total shielding from the 50 degrees C fluctuation in temperature that occurs daily on the surface of Mars.
Temperature-entrained circadian rhythms, even to a mere 2-degree C fluctuation, have been observed repeatedly on earth.
As for the original concerns of the dubious chemists, who thought the same sort of signal could simply be coming from highly reactive, non-organic
compounds in the soil, Miller says such a scenario would be almost impossible to imagine. "For one thing," he explains, "there has since been
research that shows that superoxides exposed to an aqueous solution—like the nutrient solution in the experiment—will quickly be destroyed. And
yet, the circadian rhythms from the Martian soil persisted for nine straight weeks."
"There is no reason for a purely chemical reaction to be so strongly synchronized to such a small temperature fluctuation," he adds. "We think that
in conjunction with the strong indications from Mars Observer images that show water flowed on the surface in the recent past, a lot of the necessary
characteristics of life are there. I think back in 1976, the Viking researchers had an excellent reason to believe they’d discovered life; I’d say
it was a good 75 percent certain. Now, with this discovery, I’d say it’s over 90 percent. And I think there are a lot of biologists who would
agree with me."

Also published in peer reviewed journals so i am wondering just what your objections are based on...

I know what the word means and and that's why i suggested the site in question.
Have you actually looked at it or are you just playing for time?
I'll be here all year....
The links found on that thread say pretty much the same thing...that we don't know for sure if there is or isn't life on Mars.
Please define 'for sure' and what other things you consider 'for sure' as this might just be a question of you demanding that it bites you before
admitting it's there.
And actualy, Mars Express had a lander (that failed on its landing) that has had an experiment for the search for life:
beagle 2
beagle 2 not responding
Yes; the Russians launched it for them and the lander 'failed' just like the sent a 'control' test to mars on viking that did not even work on
earth. They rig the system and i guess desperate measures is what your left with after a quarter century of inaction and general disinterest.
and unfortunetly for him, the MERs currently on Mars didn't find any liquid water.
There is overwhelming evidence for liquid water on Mars had you cared to do some research.
Why do you refuse to do any?
Recent analyses of ESA's Mars Express data reveal that concentrations of water vapor and methane in the atmosphere of Mars significantly overlap.
This result, from data obtained by the Planetary Fourier Spectrometer (PFS), gives a boost to understanding of geological and atmospheric processes on
Mars, and provides important new hints to evaluate the hypothesis of present life on the Red Planet.
Here, the concentration is two to three times higher than in other regions observed. These areas of water vapor concentration also correspond to the
areas where NASA's Odyssey spacecraft has observed a water ice layer a few tens of centimeters below the surface, as Dr Vittorio Formisano, PFS
principal investigator, reports.
New in-depth analysis of PFS data also confirms that methane is not uniform in the atmosphere, but concentrated in some areas. The PFS team observed
that the areas of highest concentration of methane overlap with the areas where water vapor and underground water ice are also concentrated. This
spatial correlation between water vapor and methane seems to point to a common underground source.

Methane either comes from dead life ( volcanism) or present life so there really is very little to argue about considering how short lived this
substance is in the Martian atmosphere.
Didn't you see the mud at the pathfinder landing site?
he he...
It's "rhythm" last i checked so maybe you want to correct your spelling after all these years of careful investigation into these 'rythms'. I am
the last one to correct someone elses spelling but i believe it might very well be saying more than you are.
