already contained some primitive RNA molecules.

|
|
contained many amino acids.

|
|
had an abundance of methane, ammonia, and water.
|
|
|
was rich in oxygen.

Detailed explanation-1: -Haldane coined the term ‘prebiotic soup’ or ‘prebiotic atmosphere’ that consisted of an abundance of methane, ammonia, and water. This term became a powerful symbol of the Oparin-Haldane view of the origin of life.
Detailed explanation-2: -The Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers.
Detailed explanation-3: -Both believed that organic molecules could be formed from abiogenic materials in the presence of an external energy source (e.g., ultraviolet radiation) and that the primitive atmosphere was reducing (having very low amounts of free oxygen) and contained ammonia and water vapour, among other gases.
