Predicates to the "origins of life"...that I posted earlier drew many
responses, some intelligent and helpfull ,and some angry...

But the basic predicates of my post remain:

1. In the vastness of time since the Big Bang and amongst the enormous
resulting cosmos, there is evidence of a singular existance of life
forms; i.e., here on Earth.

There is significante evidence of life once on Mars.

There is no way to GET evidence from outside the solar system due to the
limitations of technology.

Only a complete retard would claim us being alive was "singular evidence"

Well, I don't know what "singular evidence" means.

All I know is that we have overwhelming evidence of intelligent (semi)
life on this planet.

Yep.


Despite the ongoing search of organizations scanning the universe for
signs of life elsewhere, the search has so far turned up nil, nothing,
zero, zip.

Wrong.
Lots of evidence of life, or past life, on Mars.
I think you have been taking possibly, maybe, there is some evidence
that ----, as a certainty that there has life on Mars.

----------------------------------------------------------------
Scientists have long speculated about the possibility of life on Mars
owing to the planet's proximity and similarity to Earth. It remains an
open question whether life exists on Mars now, or existed there in the
past.

Mariner 4
The photographs taken by the Mariner 4 probe in 1965, showed an arid
Mars without rivers, oceans or any signs of life. Further it revealed
that the surface (at least the parts that it photographed) was covered
in craters, indicating a lack of plate tectonics and weathering of any
kind for the last 4 billion years. The probe also found that Mars had
no protective magnetic field, meaning that intense UV radiation makes
the planet extremely hostile to life as we know it. The probe was also
able to calculate the atmospheric pressure on the planet to be between
4 and 7 millibars, meaning that liquid water could not exist on the
planet's surface[1].
After Mariner 4, the search for life on Mars changed to a search for
bacteria-like living organisms rather than for multicellular
organisms, as the environment was clearly too harsh for these.

Viking experiments
Main article: Viking biological experiments
The primary mission of the Viking probes of the mid-1970s was to carry
out experiments designed to detect microorganisms in Martian soil. The
big difficulty of this mission was that NASA's knowledge about
conditions on Mars' surface was limited to the data returned by
Mariner 4, and so the tests were formulated to look for life similar
to the life found on Earth. Nevertheless, of the four experiments
carried out, the labeled release experiment returned a positive result
showing increased CO2 production on exposure to water and nutrients.
However this sign of life was disputed by many scientists, who argued
that superoxidant chemicals in the soil could have produced this
effect without life being present. To counter this it has been argued
that the labeled release experiment detected that there were so few
metabolising organisms in the martian soil that it would have been
impossible for the gas chromatograph to detect them. This view is put
forward by one of the designers of the LR experiment, Gilbert Levin,
who believes the results of the Viking landers are diagnostic for life
on Mars[1].

A re-analysis of the now 30 year old Viking data in the light of
modern knowledge of extremophile forms of life has suggested that the
Viking tests were not sophisticated enough to detect these forms of
life, and may even have killed it in the testing procedure[2]. The
central idea here is that instead of being destroyed by Mars' high
levels of hydrogen peroxide and other oxidants, life on Mars may use
these chemicals to help them survive. For example hydrogen peroxide
would stop water in a cell from freezing down to -50 °C and is
hygroscopic, a useful trait on such a dry planet. The researchers cite
Acetobacter peroxidans as a known example of a microbe that uses
hydrogen peroxide in its metabolism.

There are some that now argue that, if there was life at the Viking
lander sites, it may have been killed by the exhaust from the landing
rockets.[3]

Meteorites
In recent years speculation has grown as a result of studying the
ALH84001 Mars meteorite which concluded that it contained fossilized
microbes. Other scientists have subsequently sought to explain these
findings on the basis of chemical processes. Both remain highly
controversial within the scientific community. Other Mars meteorites
such as the Nakhla meteorite were suggested to have evidence of life
also but were later shown to contain no suggestion of evidence.
------------------------------------------------------------------------

All kinds of maybes, possiblys, and looks likes, but it is still a
controversy.



"Scanning" the universe cannot FIND evidence of life except through energy
emmissions.... radio, TV, microwave, etc.
Claiming "we haven't found anything" is proof that we're alone in the
universe is as idiotic as claiming you're alone on the planet because you
can't see anyone else in the room.


We may posit that absence of evidence does not mean evidence of
absence, but.....


We can look at what we see simply on Mars.
