1. **Understanding the Question**: The question asks which theory explains that the first life on Earth originated from non-living materials.

2. **Identifying Relevant Theories**:
- **Theory of Biogenesis**: This theory states that life arises from pre-existing life. Therefore, it does not support the idea that life originated from non-living materials.
- **Theory of Abiogenesis**: This theory posits that life originated from non-living substances, such as simple organic compounds found in the early Earth and oceans. This aligns with the question's premise.
- **Theory of Special Creation**: Proposed by various religious and philosophical perspectives, this theory suggests that life was created by a divine being. It does not support the idea of life originating from non-living materials.
- **Theory of Extraterrestrial Origin**: This theory suggests that life may have come from outer space, which does not directly explain the origin from non-living materials on Earth.

3. **Evaluating the Options**:
- The **Theory of Biogenesis** is incorrect because it states that life comes from existing life.
- The **Theory of Special Creation** is also incorrect as it involves divine intervention.
- The **Theory of Extraterrestrial Origin** does not address the origin from non-living materials on Earth.

4. **Conclusion**: The correct theory that explains the origin of life from non-living materials is the **Theory of Abiogenesis**.

**Final Answer**: The first life on Earth originated from non-living materials has been explained by the **Theory of Abiogenesis**.
