Have We Found Life On Mars?

NASA Mars Rover was sent to the red planet to try and discover if life exists, or once existed, on the planet and it may just have found it as it discovers high amounts of methane, on produced by living things, that suggests recent alien life as the gas breaks down within a few centuries.
The thinking is that any methane detected now must have been released recently as sunlight and chemical reactions would break up the molecules within a few centuries and they are entertaining the idea that if life ever did arise on Mars, its microbial descendants could have migrated underground and persisted.
Scientists are not confirming anything yet, stating that the findings are only preliminary and will face further investigation and even threw in the idea that geothermal reactions can also generate methane but let's pretend we never heard that last bit.
