Although there is no solid piece of evidence that proves alien life exists, i feel if we collect all the little bits of information and put it
together it paints a bigger picture..
Lets have a little look at what science has found so far...
Signals received from space
The WOW signal
On August 15th, 1977, a signal was received at the Big Ear radio observatory in Ohio. Jerry Ehman a volunteer spotted the pattern on the paper logs
circled the data and wrote “Wow!” in the margin.
The radio telescope was observing space as part of the Search for Extra-Terrestrial Intelligence (SETI) program.
The search for extraterrestrial intelligence (SETI) is the collective name for a number of activities people undertake to search for intelligent
extraterrestrial life. Some of the most well known projects are run by the SETI Institute. SETI projects use scientific methods to search for
intelligent life on other planets. For example, electromagnetic radiation is monitored for signs of transmissions from civilizations on other
worlds. The United States government contributed to early SETI projects, but recent work has been primarily funded by private sources.
The signal came from the direction of the constellation Sagittarius, and lasted seventy-two seconds at about 1420.456 MHz before it faded away
Seventy-two seconds also happened to be the exact length of time it would take for the Earth to rotate the Big Ear through a signal from space
To this day it remains a mystery and has never been heard since..

2003 SETI signal
In 2003 another signal was picked up by SETI, this time the massive radio telescope in Arecibo, Puerto Rico, picked it up.
It came from a spot between the constellations Pisces and Aries. Curiously, the signal is at one of the frequencies that hydrogen, the most common
element, absorbs and emits energy. Some astronomers believe that this is a very likely frequency at which aliens wishing to be noticed would

there is also a good chance the signal is from a never-seen-before natural phenomenon. For example, an unexplained pulsed radio signal, thought to be
artificial in 1967, turned out to be the first ever sighting of a pulsar.
A wealth of 'evidence' comes from our nearest neighbor Mars. We have to bear in mind, it is the most extensively studied planet in our solar system
and the only one we have scientific equipment on the surface, relaying information back to Earth. (mars rovers)
In 1976 tests performed on Martian soil samples by NASA's Viking landers hinted at chemical evidence of life. One experiment mixed soil with
radioactive-carbon-labelled nutrients and then tested for the production of radioactive methane gas.
The test reported a positive result. The production of radioactive methane suggested that something in the soil was metabolising the nutrients and
producing radioactive gas
The two Viking spacecraft each carried four types of biological experiments to the surface of Mars in the late 1970s. These were the first Mars
landers to carry out experiments to look for biosignatures of life on Mars. The landers used a robotic arm to put soil samples into sealed test
containers on the craft. The two landers were identical, so the same tests were carried out at two places on Mars' surface, Viking 1 near the equator
and Viking 2 far enough north to see frost in winter.
Also much evidence suggests that water once existed or still currently is on Mars..
Liquid water is necessary for known life and metabolism, so if water was present on Mars, the chances of it having supported life may have been
determinant. The Viking orbiters found evidence of possible river valleys in many areas, erosion and, in the southern hemisphere, branched
Researchers at the American space agency made the discovery after the Mars Exploration Rover Spirit became stuck in wet ground on the red planet
earlier this year. Astronomers have become excited by the latest discovery, which they say proves that water favourable for life formed on the red
planet more recently than previously thought.
Good ATS thread from TupacShakur on evidence of water on mars.
When water flows over dirt on Earth, there are certain characteristics left in the ground that follow. These structures left in the dirt are seen in
satellite images of Mars surface, leading scientists to believe that liquid water used flow on the surface.
This thread from 2008 shows images taken from Mars that show anomalies in the shapes of rocks.
These include skulls/bones/body parts of critters and alien beings and parts of what seem to be mechanical contraptions owing to their very odd
shapes. There is even an object that resembles an Uzi type machine pistol with an ammo box lying close by! Notice the shine of this ‘box’ that
seems to have a greater degree of reflection than rocks in the surrounding area. Could it be metallic?
Personally i dont buy much into these type of images as they are circumstantial rather than scientific.. but they potentially do add weight to the
The infamous Mars meteorite.
The ALH84001 meteorite was found on December 1984 on Antarctica, by members of the ANSMET project; the meteorite weighs 1.93 kilograms (4.3
lb). The sample was ejected from Mars about 17 million years ago and spent 11,000 years in or on the Antarctic ice sheets. Composition analysis by
NASA revealed a kind of magnetite that on Earth, is only found in association with certain microorganisms
The Nakhla meteorite fell on Earth on June 28, 1911 on the locality of Nakhla, Alexandria, Egypt. In 1998, a team from NASA's Johnson
Space Center obtained a small sample for analysis. Researchers found preterrestrial aqueous alteration phases and objects of the size and shape
consistent with Earthly fossilized nanobacteria
On this second sample, a large dendritic carbon content was observed. When the results and evidence were published on 2006, some independent
researchers claimed that the carbon deposits are of biologic origi
