The identification of organic molecules in rocks on the red planet does not necessarily point to life there, past or present, but does indicate that some of the building blocks were present.

The same carbon molecules, broadly classified as organic matter, also exist within meteorites that fall from space. They can also be produced in chemical reactions that do not involve biology.

This being the case, it would be inevitable that they exist on Mars, unless subsequently destroyed (for example by solar radiation).

Actually, I personally find their existence in meteorites more interesting - it tends to suggest such chemicals may be present far beyond our solar system.
