Which of the following is a major step involved in the formation of life from non living things

A. The formation of oxygen molecules.

B. The formation of water.

C. The formation of hydrogen molecules.

D. The formation of hydrogen molecules.

It is difficult to determine origin of life because of the lack of facts which supports the origin of life and theories are mostly hypothetical. But with fossil evidence and radiometric dating of the oldest rocks, we can assume that life began at least 3.5 billion years ago.

Life originated in presence of water as:

1. Geological evidence shows that liquid water might have been present on Earth 4.3 billion years ago.

2. Properties of water providing medium for reactivity, its ability for H-bonding, heterogeneous catalysis and self-organization supported life.

3.Evidence shows that earliest form of life in the tree of life were hyper-thermophilic and thermophilic complex bacteria which lived in systems composed of hot water system such as hydrothermal systems found in areas of volcanic activity.

Thus, life must have water. So, option B is the correct answer.

Which of the following is a major step involved in the formation of life from non living things A. The formation of oxygen molecules. B. The formation of water. C. The formation of hydrogen molecules. D. The formation of hydrogen molecules.
