“I think the universe must be teeming with sentient life... sooner or later we will make contact with extra-terrestrial
intelligence.”
Prof Wickramasinghe
Humans will never be able to detect extra terrestrial life forms as long as they cling to present scientific paradigms and beliefs.

I would like to clarify that this is not about advanced ETs civilizations. It’s not about their purported space ships capable of interstellar
voyages through ‘worm holes’ or even interdimensional travel and so on. It’s about evidence of fundamental extra terrestrial life forms that
have been discovered and studied scientifically. The evidence that life may be universal is being presented here in brief.
But could this be construed as incontrovertible evidence or final proof of the reality of extra terrestrial life? It could be mentioned here in
passing that what we construe as the basic requirements of ‘life’ may not be so. Much of such alien ‘life’ may be beyond our scientific
templates and knowledge on which we base our deductions.
Let’s take a look at what we’ve found and the results after scientific analyses. The first is, as usual, from the LANL archives.
The Mysterious Red Cells Of Kerala: Aliens Life Forms?

As bizarre as it may seem, the sample jars containing cloudy, reddish rainwater in Godfrey Louis's laboratory in southern India may hold...
aliens!
In 2006, Dr Godfrey Louis, a solid-state physicist at Mahatma Gandhi University, published a paper in the prestigious peer-reviewed journal
Astrophysics and Space Science in which he hypothesizes that the samples taken from the mysterious blood-colored showers that fell across the
Indian state of Kerala in the summer of 2001
contain microbes from outer space.
Specifically, Louis has isolated strange, thick-walled, red-tinted cell-like structures about 10 microns in size. However, though dozens of his
experiments suggest that the particles may lack DNA
yet they reproduce plentifully, even in water superheated to nearly 600 deg F. (The known
upper limit for life in water is about 250 deg F).
So how does Louis go about explaining this phenomenon? He speculates that the particles could be extraterrestrial bacteria adapted to the harsh
conditions of space and that the microbes hitched a ride on a comet or meteorite that later broke apart in the upper atmosphere and mixed with rain
clouds above India.
If his theory proves correct, the cells would be the first confirmed evidence of alien life and, as such, could yield new clues to the origins of
life on Earth.
Are these cell like particles a kind of alternate life from space? If the red rain particles are biological cells and are of cometary origin, then
this phenomena can be a case of cometary panspermia (Hoyle & Wickramasinghe, 1999) were comets can breed microorganisms in their radiogenically heated
interiors and can act as vehicles for spreading life in the universe.
Strangely, this episode is being under-reported. A massive investigation into this "red rain" will probably settle the question whether
extraterrestrial life exists, but why is this not happening?

According to a study published in
Scientific American, the Nakhla meteorite that fell in Egypt nearly 95 years ago may offer clues as to the
search for possible extra terrestrial life. Researchers studying the meteorite that originated from Mars found a series of microscopic tunnels within
the object that mimic the size, shape and distribution to tracks left on Earth rocks by the feeding frenzy of
bacteria.
The discovery of the tiny burrows adds intrigue to the search for life beyond Earth. However, no DNA could be extracted from the meteorite, so it's
not known if the tunnels are of biological origin.
But the research findings of a team of scientists led by Martin Fisk, a professor of marine
geology in the College of Oceanic and Atmospheric Sciences at Oregon State University), published in the February issue of the bimonthly journal,
Astrobiology, insists the lack of DNA does not derail the prospect.
Subsequently, scientists had decided these structures most likely represent contamination from Earth-dwelling biota. But now the BBC is
reporting that researchers from the U.K. have cracked open the meteorite from Egypt and found material that resembles the filling left behind by
microbes in cracks on the bottoms of the ocean. Solid veins of such “carbonaceous material” were found inside the meteorite, quashing objections
that it could represent contamination from contact with earth, the researchers claim.
And according to the BBC, previous scientists who examined the rock found that more than 75 percent of the meteorite's carbon is not one of the most
common isotopes of carbon--carbon-14. That means it could be the relic of the action of alien microbes toiling in unimagined seas on ancient
Mars.

Some of the first possible extra terrestrial proofs of life came in 1996 from a meteorite found in Antarctica. Ejected from the surface of Mars it
came to rest on Earth, bearing odd, microscopic structures that resemble fossilized remnants of bacteria.
The indication of life hinges on three important pieces of evidence, all discovered within mineralized fractures in the meteorite in close
proximity to each other. One is the discovery of abundant polycyclic aromatic hydrocarbons (PAHs) on the fracture surfaces. These are a family
of complex organic molecules which are commonly found on dust grains and certain types of meteorites in outer space, presumably formed by
non-biological chemical reactions.
However, when micro-organisms die they break down into PAHs as well. The mixture of PAHs found on ALH84001 is very different from that found on
dust grains and other meteorites, suggesting the possibility of a biological origin. Thousands of different types of PAHs are found all over the
Earth, but those in ALH84001 do not appear to be contaminants which have leaked into the meteorite.
Further,
high-resolution scanning with electron microscopes had revealed the presence of tiny "ovoids" which may actually be fossil remnants of
tiny bacteria that are 100 times smaller than any bacteria microfossils found on Earth!

Evidence Of Life In Outer Space: Space Bugs.

In 2001, a team of international researchers found what could be the first proof of life beyond our planet, in the form of clumps of extraterrestrial
bacteria in the Earth's upper atmosphere! Although the ‘bugs’ from space are similar to bacteria on Earth, the scientists said the living cells
found in samples of air from the edge of the planet's atmosphere are
too far away to have come from Earth!!
According to Professor Chandra Wickramasinghe, an astronomer at Cardiff University in Wales…
“There is now unambiguous evidence for the presence of clumps of living cells in air samples from as high as 41 kilometers (25 miles), well
above the local tropopause, above which no air from lower down would normally be transported.''.
He presented the findings to a meeting of the International Society of Optical Engineering in San Diego, California. Professor David Lloyd, a
microbiologist at Cardiff University who examined the space bugs, says,
“The most likely possibility is that the bacteria have arrived from
another planet. I'd like to think that, at any rate. It's the first pointer that it is possible to get evidence that there is life on other
planets.''
"When you look at the detailed nature of life in terms of molecular complexity it seems extremely unreasonable to suppose that on this tiny speck
of dust - which is all that the Earth is - the most complex physical system originated.”

Methane in the Martian atmosphere hints at microbial metabolism
In 2004 three groups - using telescopes on Earth and the European Space Agency's Mars Express orbiting space probe - independently turned up evidence
of methane in the atmosphere.
Nearly all methane in our own atmosphere is produced by bacteria and other life. Could this mean that the
methane on Mars is being produced by organic life? Most likely. More

Amino Acids And The Murray Meteorite.

This meteorite is a Type II carbonaceous chondrite that fell near Murray, Kentucky, in 1950. Its analysis by Melvin Calvin provided early support for
the idea that
prebiotic molecules can form in space. As many as 70 different kinds of amino acids have been found in the Murray meteorite
With the help of a detection technique known as gas chromatography-mass spectrometry, the researchers identified a number of so-called
polyhydroxylated compounds, or polyols�including sugars, sugar alcohols and sugar acids�in extracts from the two meteorites. Reassuringly, the
fact that these sugar-related compounds display many of the characteristics of known extraterrestrial compounds speaks against the possibility of
terrestrial contamination. Furthermore, the team's findings indicate that extraterrestrial processes can account for the sugars.
These results suggest that these amino acids, are most likely extraterrestrial in origin.
So what do you make of all this? Can life be abundant in the universe? Could we have originated from out there? Are we the aliens?
Cheers!
