Firstly formation of life occurred in :

Options

A. Water
B. Air
C. At `800^(@)C` temp.
D. In Vapour state

Answer

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

1. **Understanding the Environment for Life Formation:**
- The formation of life is believed to have occurred in a primordial environment that was rich in various gases. This environment was primarily aquatic.

2. **Role of Primitive Atmosphere:**
- The primitive atmosphere consisted of gases such as hydrogen, nitrogen, and oxygen. These gases were in atomic or molecular forms and were crucial for the chemical reactions that led to the formation of life.

3. **Cooling of the Earth:**
- As the Earth cooled down from extremely high temperatures (approximately 800 degrees Celsius), the conditions became suitable for chemical reactions. This cooling allowed for the formation of liquid water.

4. **Formation of Water:**
- In this reducing atmosphere, hydrogen and oxygen combined to form water (H2O). The presence of water was essential as it acted as a medium for various chemical reactions.

5. **Formation of Organic Compounds:**
- After the formation of water, various molecules began to interact. The first organic compound formed in this aquatic environment was ammonia (NH3), followed by methane (CH4).

6. **Development of Amino Acids and Polysaccharides:**
- These organic compounds further reacted to form amino acids, which are the building blocks of proteins. Additionally, methane contributed to the formation of carbohydrates, leading to the creation of polysaccharides.

7. **Conclusion:**
- Therefore, the initial formation of life occurred in water, which is often referred to as the "hot dilute soup" where these essential chemical reactions took place.

**Final Answer:**
The formation of life firstly occurred in water.
