So the instruments on board the rover may have found signs of organic molecules. Still not clear what it is and they aren't saying anything yet. In my opinion if they find amino acids or dna bases it has to point to life. Those molecules don't occur outside of biological systems.
What would be even cooler is if the amino acids have the same stereochemistry (the way the atoms are positioned) as the amino acids on earth. That would imply that life in our solar system has a common origin. Could it be life evolved on Mars first and was transported to earth via meteorites in the early history of the solar system?
earth shaking news if that's what it turns out to be.

Reason: merged threads
The meterorites carrying molecules to Earth and creating life is a theory some do believe and carries merit. I'm not expert and I've barely scratched the surface on anything relating to this, but I believe "life", or variations of it can survive and a multitude of locations.
For example, creatures live very deep in the water. Places we think would be uninhabitable for virtually anyone/anything by way of chemosynthesis.
A form of life on Mars isn't unexpected imo, but rather... "intelligent" would be.
NASA's Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing substances, among other ingredients, showed up in samples Curiosity's arm delivered to an analytical laboratory inside the rover.
Detection of the substances during this early phase of the mission demonstrates the laboratory's capability to analyze diverse soil and rock samples over the next two years. Scientists also have been verifying the capabilities of the rover's instruments.
Curiosity is the first Mars rover able to scoop soil into analytical instruments. The specific soil sample came from a drift of windblown dust and sand called "Rocknest." The site lies in a relatively flat part of Gale Crater still miles away from the rover's main destination on the slope of a mountain called Mount Sharp. The rover's laboratory includes the Sample Analysis at Mars (SAM) suite and the Chemistry and Mineralogy (CheMin) instrument. SAM used three methods to analyze gases given off from the dusty sand when it was heated in a tiny oven. One class of substances SAM checks for is organic compounds -- carbon-containing chemicals that can be ingredients for life.
NASA won't change. Enthusiasts have to learn how to filter the marketing drama, much like we learn to do with ads and tv commercials. Part of these dramatic announcement techniques are meant pique our interest amid tons of other daily PR memos waiting to be picked up (hopefully) by various news feeds and media outlets. Scientists have learned to capture attention with terms like the 'God Particle'; bylines like '7 minutes of terror' work better than atmospheric entry. Public research institutions also need public funding and public acceptance. Looking for ET life is exciting and dramatic, basic scientific analysis a bit more mundane. Get used to the marketing hyperbole, it isn't going to stop anytime soon, in advertising or space.
A while back I took a road trip to Rochester NY starting at 11pm. On the way I was lucky enough to catch "Coast to Coast AM" and the entire show was dedicated to rather far fetched theories based on speculations of shapes coming from Mars Rover photos. The conspiracy bandwagon's loosely guided fantasies alone make the trip to Mars worth it.
so it's a sword stuck in a rock? Pull it out! The rover will become king of the universe.
