The Earth's surface is made up of 71.11% water. Only 3% of that is freshwater, the rest is seawater. The earth began by: Lightening provided energy to fuse the gases into different amino-acid particle Amino-acid particles collide with another to for protein particles Protein particles collide with one another to form a living cell. At first, life was very simple and consisted of "self repeating particle". Later, life learned to store genetic information in DNA particles: single cell organisms (bacteria). The middle of the earth is made up of mantle. The mantle is approx 2885 kilometres thick and is the middle layer of the earth. The mantle is made up of minerals rich in the elements iron, magnesium and oxygen. The mantle make up approximately 85% of the earth's volume.

My question to you is this. Who made the lightning and the gasses? I think you might need to do some research on DNA.

@IreneVincent That is indeed the million dollar question. There is a very interesting book by Laurence Krauss called "A Universe From Nothing" which causes us to completely rethink our concept of 'nothing' and offers a scientifically plausible explanation as to the origins of the universe from 'nothing'. Very simplistically it's to do with Heisenberg's Uncertainty Principle and the, yet to be proven, assumption there exists an uncertainty relationship between gravitational energy and time thus allowing a universe with net zero gravitational energy to exist for an infinite time. The theory is that universes are continually popping into existence from this 'nothing' but those with a non-zero net gravitational energy only exist for tiny fractions of a second as would be the case according to Heisenberg's Uncertainty principle. But guess what? We lucked out! Our universe has zero net gravitational energy. It's at this point I find myself agreeing with you. How did that 'nothing' get there? Who, or indeed what, put it there? I can understand that this question could lead to the answer 'God' for many people. However, I find this a way too convenient and simplistic answer. For me this just raises the question "Who or what put God there to create this 'nothing'" and only leads me to think that Bertrand Russell's old-lady inquisitor was onto something with her 'It's turtles all the way down' remark.
