Fascinating.

"Journal of Cosmology"

Yeah, no. That journal has published alien fossils which were then refuted. No one takes them seriously.

Phew! For a minute there I was worried you wouldn't pop in here to piss all over my hopes and dreams.

Didn't we find a meteorite from Mars with fossilized microbes, back in the 1990's?

You're talking about this: http://en.wikipedia.org/wiki/Allan_Hills_84001
and the answer there is.... um, maybe. It's not conclusively alien though.

Seems to be leaning more to it containing fossilized microbes of Martian origin, though.

I wonder why people stopped talking about it after 1996?

Later, however, the same authors published papers supporting a hypothesis in which the globules formed at low temperature from an aqueous solution. Most scientific papers published in the past 10 years now accept that carbonates on Mars formed this way.[14]
Other initial skepticism towards the biogenic hypothesis focused on the idea that the nanometer-sized filaments were too small to contain RNA, but evidence continues to grow that nanobacteria do exist in nature.[15][dubious – discuss] Furthermore, microbiologists have successfully cultured nanobacteria in the lab, with sizes within the range of at least some of the purported microfossils in ALH 84001.[16][dubious – discuss] Some[who?] experts argue that the biomorphs found in the meteorite are not indicative of life on Mars, but instead are caused by contamination by terrestrial biofilms. However, scientists at NASA argue that likely microbial terrestrial contamination found in other Martian meteorites do not resemble the texture of the biomorphs in ALH 84001. In particular, the biomorphs in ALH 84001 look intergrown or embedded in the indigenous material, while likely contamination do not.[14]
While it has not yet conclusively been shown how the features in the meteorite were formed, similar features have been recreated in the lab without biological inputs by a team led by D.C. Golden of Hernandez Engineering Inc. in Houston.[17] David McKay says these results were obtained using unrealistically pure raw materials as a starting point,[6] and "will not explain many of the features described by us in ALH84001." According to McKay, a plausible inorganic model "must explain simultaneously all of the properties that we and others have suggested as possible biogenic properties of this meteorite."[17]
In November 2009, a team of scientists at Johnson Space Center, including David McKay, reasserted that there is "strong evidence that life may have existed on ancient Mars", after having reexamined the meteorite using more advanced analytical instruments now available, in light of the objections that had been made since the biogenic hypothesis for the biomorphs first had been put forward.[18][19] Overall, the team concluded that:

None of the original features supporting our hypothesis for ALH84001 has either been discredited or has been positively ascribed to non-biologic explanations.[14]
In addition, they argued that since the original paper was published, the biogenic hypothesis has been "further strengthened by the presence of abundant biomorphs in other Martian meteorites."[14]

It's not conclusively proven yet, but the evidence so far seems to point to yes, if this summary is accurate.
