**Step-by-Step Text Solution:**

1. **Understanding the Cosmozoic Theory**: The Cosmozoic theory suggests that life did not originate on Earth but was instead brought to our planet from outer space. This theory posits that life exists throughout the universe and can be transferred via space dust, meteorites, comets, or other celestial bodies.

2. **Identifying the Proponents**: The Cosmozoic theory is closely associated with the concept of panspermia, which is the idea that life can be distributed across the universe. The scientists who proposed this theory are Richard and Svante Arrhenius.
