Select the incorrect statement among the following.

We have no idea about how the first self replicating metabolic capsule of life arose.

The first non-cellular forms of life could have originated 3 billion years back. They would have been giant molecules (RNA, Protein, Polysaccharides, etc.). These capsules reproduced their molecules perhaps.

The first cellular form of life did not possibly originate till about 2 million years ago. These were probably single-cells. 

All life forms were in water environment only. This version of biogenesis, i.e., the first form of life arose slowly through evolutionary forces from non-living molecules is accepted by majority.
