It comes from water.

In short water is a reason to life on EARTH. What ever, water is all around. Health experts speak about increasing body mass, actually speaking they increase the water retention capability of our body. 85% of the body mass of any living creature on this EARTH is WATER.

You don't trust me? Would you like to try it out yeah?

If yes then it is a lethal test.

Wanna try it or ever tried on others?

It's definitely water. This question was answered by Samuel Rubin's experiment in 1940's.

In 6 molecules of water only 6 oxygen atoms are present and 12 oxygen atoms are required to make 6 oxygen molecule. So alone from water we could not get the required no of atoms. So oxygen from CO2 will also be required to complete the reaction.
