'Life on Mars' Meteorite Rejected After 10 Years
An anonymous reader writes "Ten years ago, NASA announced that the Martian meteorite ALH84001 showed evidence of life on Mars. The announcement made headlines around the world, and even prompted President Clinton to make a statement. Ten years later, most scientists believe that everything in the meteorite can be explained by non-biological processes. "We certainly have not convinced the community, and that's been a little bit disappointing," said David McKay, a scientist behind the 'life on Mars' paper. Unfortunately, David McKay's own brother is one of his critics. "He [David] got a little testy about the results we were getting," said Gordon McKay. "What we have shown is that it is possible to form these things inorganically.""
No one wants to admit life started out there somewhere. For all we know the meteorites seeded life on Earth... and elsewhere. Why is it so hard for people to believe life exists beyond earth?
Just because people believe life started elsewhere doesn't mean that this rock is an example of life. Wanting life to exist elsewhere does not account for good scientific judgement. I fear that Mr. McKay has much of the former but little of the latter.
This stuff is science, not religion. All that's being said in the article is that there are explanations for the contents of that chunk of rock other than life. That doesn't rule out the possibility that life was involved, but it does rule out the meteorite as proof that there was life. So, we're back where we were before: no one knows for sure.
Just because these things can be formed inorganically doesn't mean they were. Still the burden of proof definitely rests on those who says it is organic in origin. Especially now.
Luckily, just because the meteor may not have signs of former life, doesn't mean mars never had any. It would be really sad if our solar system turned out to be sterile.

Er, exactly how would life begin on a meteorite? Exactly what chemistry would allow that to happen? I think it's a tad more likely that life would begin on a planet with the requisite natural resources.
The probabilities and facts dictate the earth is not the center of the universe.
We have absolutely zero evidence for life on planets other than earth. On the other hand, we have considerable evidence that we're alone in the galaxy (other galaxies are too far away to know anything about).
I for one think it would be good for mankind to have a significant first contact with a superior race. At least then we can then look to exploration and not war to keep us occupied while we grow up.
I for one think magic wands would be good for mankind as well. Then we could keep busy with our wands and not war. It would also eliminate resource limitations, which are fundamentally the reason for war. Magic wands are about as likely as alien life, so why not go for broke?
Sometimes it's best to just let stupid people be stupid.

So far the theory of panspermia is very far from proven, and the most widely accepted theory about the formation of life on earth is not panspermia but chemical reactions forming aminate acids, or somethnig of this kind.

When it comes to science, thou shalt ban the verb 'to believe' out of thy vocabulary.

Why do people systematically consider that an extraterrestrial race would have to be superior to us in the same way that we are superior to the rest of animals? Keep us occupied while we grow up? What's making you think that we're growing up? Our nature is immuable, the only way we can give ourselves the feeling of evolving is through the evolution of our civilization, but that's not going to make us closer to any hypothetical superior extraterrestrial race, if there even can be such a thing as animals significantly superior to us. It seems that the idea of us being probably the most evolved life form possible has went through relatively few people's minds.
Back to the topic, scientists have no trouble admitting some forms of life might exist or might have existed in the universe, even inside our very own solar system. But the object of this article is about determining whether this precise piece of rock reveals the existence of any actual extraterrestrial form of life, it's not about determining whether there could or could not have been life in the Universe, nor even on Mars.
It's all about this precise rock.
You just got troll'd!
