Recently, the latest data analysis of the Aeronautics and Space Administration in a certain country confirmed that the signal detected by the Curiosity Mars rover on Mars in June 2013 was a methane signal. Based on this, some people inferred that the methane may come from organisms living in Gale crater, which indicates that there must be life on Mars.
The statement 'Methane on Earth will quickly disappear into the atmosphere after being produced by organisms, which proves that methane on Mars must have just been released soon' would most question the above inference.
