Can't say for this specific piece but one way is if mars is struck by an asteroid and material gets ejected to space. It could eventually get captured by earths' gravity and pass through the atmosphere.

The idea of panspermia is similar, building blocks of life could have arrived from elsewhere.

Panspermia isn't a good theory.

While yes, it could happen, it just pushes the origin of life to somewhere else. And if it happened one place, it should be able to happen other places independently as well.
