Did the Perservance Rover find life on Mars?

The headlines would certainl;y suggest that they did.

But the truth (as always) is a little more complicated.  What they found were possible bio signatures.

"The combination of these minerals [ iron-containing minerals vivianite and greigite], which appear to have formed by electron-transfer reactions between the sediment and organic matter, is a potential fingerprint for microbial life, which would use these reactions to produce energy for growth."

These samples were collected after analysis, and will be part of the payload that NASA intends to return to Earth at some point in the not-too-distant future.  These samples will then be analyzed here on Earth, and we can decide if they do, in fact, indicate there is life.  

So for now, set aside the hyperbole.  It may be that these are building blocks.  But we won't know for at least a few years.
