There seem to be lots of things missing or that just plain don't work.
That's not a question. Its a statement. It's an honest mistake to be sure, but maybe its a sign that you should start spending more time thinking about how you might improve yourself and a little less time nitpicking every little detail of any given website.

NASA: Evidence of life on Mars


NASA scientists have produced the most compelling evidence yet that bacterial life exists on Mars.

It showed that microscopic worm-like structures found in a Martian meteorite that hit the Earth 13,000 years ago are almost certainly fossilized bacteria. The so-called bio-morphs are embedded beneath the surface layers of the rock, suggesting that they were already present when the meteorite arrived, rather than being the result of subsequent contamination by Earthly bacteria.

Scientists were able to trace the meteorite back to Mars, as its chemical composition matched the relative proportions of various gases measured in observations of the atmosphere of Mars made by the Viking spacecraft in the 1970s.

The meteorite also preserves evidence of liquid water on Mars, suggesting that the planet may have had more suitable conditions for life to develop in the past.

I remember this hitting the news 10 years ago; cool to see that the initial theories are coming closer to being confirmed. It's also neat how they were able to determine that this fossil was a meteorite of Mars in the first place; both by the chemical analysis and just by the simple chance that it was found at all.

apparently there is some chatter in the catholic church amongst the tards about how to handle the issue of life on other planets...as in - evidence is coming to prove it, so we need to find a way to make our religion agree it exists without admitting we have been wrong about everything.
