What evidence do we have for the origin of life from inanimate matter?

Explanation

**Step-by-Step Solution:**

1. **Introduction to the Concept**: The question asks for evidence supporting the idea that life originated from inanimate matter. This concept is rooted in the theory of abiogenesis, which suggests that life arose naturally from non-living matter.

2. **J.B.S. Haldane's Hypothesis**: A British scientist named J.B.S. Haldane proposed that life originated from simple inorganic molecules. He theorized that the early Earth was a hot gaseous mass containing essential elements like nitrogen, oxygen, carbon, and hydrogen.

3. **Formation of Simple Molecules**: According to Haldane, as the Earth cooled, these elements combined to form simple molecules such as water (H2O), carbon dioxide (CO2), methane (CH4), and ammonia (NH3).
