It's not possible, only life can do this.
demand extraordinary proof.
That's a Basic Rule of Skepticism, BTW.

You didn't answer my question, can you explain that picture
with a non living explanation? I've tried, so have many
respected researchers, and many come to the conclusion
only microbial life could explain the data.
Not paying attention, are we?
/You/ are making the extraordinary claim.
The burden of proof is on /you/.
And handwavium and chanting the mantra "only living organisms could do
it" is /not/ proof.
Myself, I will wait until the actual /scientists/ decide what did it.
Did you read the papers I included where many esteemed scientists said
they must be from life ???????????????
You'll be waiting forever if you utterly refuse to read what
scientists are saying about them. I'm not making this stuff up
read below, that is if you can read. Right now I'm not
convinced your reading comprehension is adequate to
Martian 'blueberries' could be clues to presence of life
Previous theories suggested these concretions were formed
by simple chemical reactions without the help of life.
However, new UWA research shows clear evidence that microbes
were essential in their formation.
This raises the possibility that Martian "blueberries" may
not only reveal that water was present on Mars - but life too.
UWA scientists David Wacey and Matt Kilburn used
high-resolution NanoSIMS technology at the University's
Centre for Microscopy, Characterisation and Analysis to
show clear relationships in the Utah concretions between
microbe-like forms and concentrations of biological
elements such as carbon and nitrogen.
Their findings - in collaboration with scientists from
the University of Nebraska - feature on the front cover
of the August issue of the journal Geology.
University of Nebraska Assistant Professor Karrie Weber
said UWA's CMCA facility - which is used to study
everything from early life on Earth to cancer drugs,
plant biology, rocks and soils, and nanotechnology
- was chosen because of its demonstrated success in
identifying microbial fossils.

Putative Martian Microbes Formed Plentiful Ooids on Mars
Journal of Astrobiology & Outreach 04(01)
NASA’s Mars Rover Curiosity discovered plentiful indigenous
spherical ooids at High Dune and Namib Dune in Bagnold dune
field, Gale Crater, Mars. Closely resembling ooids of Earth,
the Martian ooids are spherical in shape, similar in size,
mostly about 0.5 mm in diameter. Colors of the Martian ooids
are various, including white, yellow translucent, green, grey,
and yellow. The Martian ooids should have been formed by
microbes, because ooids of Earth have recently been found
to be formed by microbes and microbial borings are found
in ooids of Earth and Mars.
The Martian ooids are unlikely to have been formed by
non-biological mechanisms, because there was no highly
agitated water at the discovery sites.
Evidence of Life on Mars?
1. Overview: The Evidence
Presented here is a body of evidence and observations which
do not prove but supports the hypothesis Mars was, and is, a
living planet hosting prokaryotes, lichens, and fungi.
This evidence includes:

Possible organosedimentary structures on Mars
Our study shows that such laminated sediments and the spherules
they contain could be organosedimentary structures, probably
produced by microorganisms.
Possible microbial signs on martian rocks
“Since 2009 it has been pointed out that the sub-millimetric laminae
of martian sediments and the nicknamed blueberries (haematitic
spherules of millimetric dimensions) were not homogeneous but,
really, formed by structural aggregations of smaller
micro-spherules (from 1/10 mm to 3/10 mm).
By this way the imagine texture is, really, a genetic marker
depending on the sedimentary environment and bacterial activity.
This analysis, realized within a set of 40 couples of images
from martian rovers and from museum microbialite samples,
has highlighted the presence of intriguing textures made
by crossed filaments with close morphological parallels
at the same observation level”.
In the last years, these microstructural relationships have been
studied in detail: “University of Siena has performed an analytical
and multifractal approach of image couples whose results showed
that these images are absolutely alike. Another morphological
study conducted by Laboratorio de Investigaciones Microbiológicas
de Lagunas Andinas (LIMLA) on living microbialite samples, coming
from Atacama desert (Chile), has allowed to show, through their
organic pigmentation that these microstructures really exist and
are a product of bacterial metabolism” Rizzo goes on.
“However, as structures at meso and macro levels are
considered distinctive for microbialites identification, in
this late study the microscopic analysis has been integrated
with detailed observations at larger scales. The number, the
variety and the peculiarity of collected data confirm, in
a firm way, that such relationships are not pure coincidence”.
