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.
Methane found on Mars may be caused by the impact of meteorites, causing the methane gas stored in the ground to be continuously released would most question the above inference.
