They are thought to have been ejected from Mars due to impacts, striking the surface of the planet. Mars has a thin atmosphere in comparison with the Earth, we may also note. Scientists have said some of the rocks are surprisingly young. It deosn’t actually say how young.

One by the former president of the Archaeological Institute of America and another by Robert Hermes of the Los Alamos National Laboratory. They concern Younger Dryas airbursts which are compared to nuclear detonations in the low atmosphere. This idea appears in Nicholas Costa’s book, ‘From Adam to Apophis’.
These articles are published in a new journal, ‘Airbursts and Cratering Impacts‘ volume One issue One [an open access journal].
At https://www.livescience.com/space/asteroids/the-sun-is-blinding-us-to-thousands-of-potentially-lethal-asteroids-can-scientists-spot-them-before-its-too-late … the glare of the Sun, through telescopes, inhibits astronomers from seeing space rocks approaching earth. Infrared telescopes are now being employed – or are planned. The 2013 Chelyabinsk meteor arrived from behind the glare of the Sun and was not seen until it was too late.
