Post by DocUFODonnie told Rogan that Mars might have aliens despite no evidence
to date the Red Planet has any advanced life forms or ever has had.
#1. The Mars Lander's test for life, which came back positive.
If you Google it there's plenty of non-life explanations for the
results but isn't that always the case?
"Let's spend a billion dollars, in 2024 dollars, on this test that
100% guarantees to answer the question about life on Mars. Wait,
what? It came out positive? Well it's not so iron clad and, gee,
I bet you wished I said something BEFORE building, promising it's
guaranteed & flewing it to Mars."
#2. Biosignatures in the atmosphere.
I remember when they turned these methods on earth, from space,
the headlines claiming that they "Proved" there is life on earth.
Well, just as soon as they got their positive result from Mars
it was denounced as a useless test.
Methane, even oxygen! Neither can remain in an atmosphere for
very long. Oxygen loves to react to things, LIKE METHANE! So they
need to be replenished.
#3. The famous Mars Rock
Back in the 1990s it was declared that a Martian meteorite
contained micro fossils! The fossils were later tested using
a method described as fool proof, 100% conclusive, right up
until it returned a positive result on the Mars Rock "Fossils."
From then on it was only "fool proof" in the case of earth rocks.
#4. Photographic evidence
There are a great many photos taken on the surface of Mars of
structures, stains (etc) that appear as life. All of these have
non-life explanations, some of them even good, but without a
return mission & thorough testing there is no way to tell.
#5. Indirect evidence
Mars is believed to have cooled more quickly than the earth and
to have supported a very earth like environment in the very
distant past. It's difficult to believe that life may have spawned
on the barren hellscape that is the present day Mars but that is
NOT what anyone is suggesting.
The model suggested is that life arose on a wet, far warmer Mars,
perhaps even reaching into the realm of macrobiology, only for
Mars to slowly watch it's surface stripped away. Life would have
gradually gone extinct, save for extremaphiles clinging on under
the surface and perhaps under rocks or in crevices above ground.
Personally I think it EXTREMELY likely that Mars hosts life. For
me the only question is if it is indigenous life or contamination
from any number of machines sent to & towards Mars.
To me, the best evidence for indigenous life on Mars would be
Macrobiology -- something large enough to be seen with the naked
eye. It seems extremely unlikely to me that in the short time
span humans have been launching technology in the direction of
Mars that microbes could have evolved into something the size of
even small insects.
A fossil life form of any size, dated with a period prior to life
on earth, would also work, though a macrofossil would again be
the best evidence.
