Explanation

**Step-by-Step Solution:**

1. **Identify the Experiment**: The experiment in question was conducted by Stanley Miller and Harold Urey to support the theory of the biochemical origin of life.

2. **Understand the Background**: The theory of chemical origin of life was proposed by scientists Alexander Oparin and J.B.S. Haldane. They suggested that the early Earth's atmosphere contained certain gases that could lead to the formation of organic compounds.

3. **List the Gases Used**: In their experiment, Miller and Urey used the following gases:
