‘Martian Methane Reveals the Red Planet is not a Dead Planet’ NASA Article
 

NASA article about discovering methane on Mars shows that there is some sort of biological or geologic activity there.

The "bacteria" in the meteorite turned out not to be bacteria at all....
I quote from the link you offered us:

"In July, 1996, it was announced that Dr. David McKay, along with a team of scientists at Johnson Space Center (a division of NASA), had discovered possible fossils of bacteria in a meteorite named ALH84001 that came from Mars. It was found in the Allen Hills in Antarctica in 1984 after having landed there 12,000 years ago. While many scientists were excited at first, much of the proof offered fell apart. NASA said that after two years of study "a number of lines of evidence have gone away".

Several different chemicals and molecular structures were exciting because they looked similar to byproducts of life on Earth. However, these chemicals and structures can also be created without life. Some are even present in deep space on comets, and scientists do not think that they came from Martian life anymore.

Small spheres were observed in the meteorite which the scientists in 1996 claimed were the fossilized remains of bacteria. However, they are roughly 1000 times smaller than the smallest bacteria on Earth, so don't resemble any life thought to be possible. Organic (carbon containing) compounds were found with the spheres, but it turned out that the organic compounds became a part of the meteorite after it landed on Earth (possibly when water seeped in a couple times over the 12,000 years the rock laid in Antarctica). Carbon 14, an isotope found on Earth is present in the organic compounds, but not in the spheres."

To date, no signs of life have been found anywhere but on Earth. Certainly there is "life out there"; we just haven't found it yet.

Short video, full of information on how life may have very well originated on Mars. Evidence in found Meteors containing microbal fossils.

"Panspermia hypothesis"

From Wikipedia

"It is hypothesized that large asteroid and cometary
impacts on Earth's surface may have caused fragments of
microbe-laden rock to escape Earth's gravity, suggesting
the possibility of transpermia.
Calculations indicate that a
number of these would encounter many of the bodies in
the Solar System, including Titan."

"On the other hand, Jonathan Lunine has
argued that any living things in Titan's cryogenic
hydrocarbon lakes would need to be so different
chemically from Earth life that it would not be possible for
one to be the ancestor of the other.[145]"


On the other hand...


Microbal lifeform has been found in California's Mono Lake", which thrives on Arsenic. Not Phospherous, as other microbal life.

Echoing Robert Lazar's statements, of Area 51 fame...

NASA findings indicate water was prevalent in abundance from one area of research by the Rover.




Related to the "Face" and, "Pyramids" on Mars? Also, regarding biological origins... that we are actually, "Martians"?

My opinion is that Intelligence and Consciousness exists apart from physical form.
To be equated with Light.

So, yes, you make a good point, but, you are referring to something, then, which is non physical. No?

All terrestrial planets life is possible.
