How can meteorites be interplanetary arks?

Answer 1

Theory of Panspermia says that life forms like microbes could travel in meteorites and reach other planets seeding life there.

Since mars being a smaller planet, it cooled earlier than earth and life forms originated there first. The huge meteor hit on mars surface will throw away material at mars escape velocity, the material will orbit Sun and later will reach earth thus spreading life to earth.
