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.""
