NASA ’s Perseverance rover made a groundbreaking discovery on Mars last summer .

Scientists can't be sure that the signals are 100% attributable to organic molecules.

Many scientists believe the discovery could hint at the possible presence of ancient extraterrestrial life.

The uncertainty comes down to the rover's instruments — they can provide strong indications and gather valuable data.

The presence of aromatic organics would be more likely to be found in the Jezero Crater .

However, even if organic molecules are present, this doesn't mean they are a potential sign of life.

On Earth , ambiguous results like these can be clarified by using different analyses to corroborate the findings.
