Evidence of life on Mars

The question of the possibility of life on mars comes when scientist discovered the meteorite in 1996, in Antarctica. This meteorite contains organic molecules.

All the major space Agency launched much mission to know more about the mars. NASA also send two launched two operations on Mars named Opportunity and Curiosity.

Water on mars: – Some pictures taken by opportunity and curiosity make it clear that there is water stream on Mars. Curiosity found some round pebbles on mars, which resembles the pebbles found on earth, they tend to be very round as well because as they move in the stream pebbles are hitting another pebble.

Curiosity also found some organic chemical which shows evidence of life on mars in Past. It may be possible that Mars was habitable before Earth was.
