The world is more than rocks. Your brain is a rock?
The world have rocks, water, gases, energy. In the world there are near 90 elements that can combine to form molecules. Some molecules are very complex and can make a copies of itself. Those molecules works together as a team, giving LIFE to a cell. That's is the LIFE.

The world was not really "created" by 'rocks'. The world was created by chuncks of elements and lots of stuff orbiting the sun. Then, when the world had a completely different atmosphere than it does now, organic compounds (amino acids) were created.
This can happen when a strong electrical current (such as lightning, which the Earth had plenty of when it was young) goes through what the atmosphere was like back then. -Think Stanley Miller-.
After a while, some of those organic compounds were able to form into 'proto-cells', or cell-like clumps of organic materials that are not alive, but can reproduce.

Then, by chance, if even only ONE of those actually slowly became more advanced and became 'alive', life on Earth could be started.

When the early cells began to create and use chlorophyll, oxygen began to fill the atmosphere over MILLIONS of years. With oxygen as an efficient energy resource, more complex organisms were able to evolve and survive.

(About the oceans, water was very common on Earth after it cooled down a bit from its hot early stages.)

maybe it's better to follow the evidence. we have pretty good evidence about the state of the world now. we observe that life evolves, and infer that the same has happened in the past. plants and animals apparently evolved from different single celled species. (fungi probably split off from animals after they became multicellular, and some marine 'plants' such as seaweeds may have independently evolved multicellularity).

how cellular organisms evolve from 'lifeless' chemicals is a bit mysterious. what is life anyway? we can define it by what it does - it has boundaries such as the cell membrane, or for multicellular life, skin. it has heredity, that is it's capable of producing almost perfect copies of itself. it has metabolism, it can absorb energy and matter for its own uses. these properties and processes are all mediated by chemicals, life is a fundamentally chemical phenomenon. the difficult part is to answer how they came together, doubtless in a much simpler chemical system than current life. this is the problem of abiogenesis. some researchers believe that metabolism came first, while others say the heredity (genes) must come first. both camps seem to leave out the membrane, which is arguably more fundamentally important in the conception of 'life' than the other two: heredity and metabolism lose their meaning without a membrane to separate the organism from its environment.

so 'created by rocks' doesn't really enter the picture. it's a little more complicated than that, at least.

The world was not "created" by rocks. It is made up of rocks (partly), but it's also made up of liquids and gasses.
(Also, try to avoid using the word "created." Even though it may be a perfectly good word, unfortunately these days it has religious / supernatural mythology connotations, and turning to religion and mythology to answer questions about the nature of reality will get you nowhere.)

What you are really asking is, "how did replicating organic matter (life) form from inorganic chemical compounds?"

Good question. Scientists are working on figuring this out.
Here's what we know so far:
1) Inorganic chemical compounds are capable of spontaneously replicating themselves provided the right chemical conditions are available - it's called crystallization and it happens all the time and it can be reproduced in the lab.
2) Chemical compounds made of organic matter also replicate themselves using crystal growth processes. This has also been observed in nature and in the lab.

So, it's not a huge leap of logic to assume that the type of replication that is produced by chemical crystallization processes could lead to the formation of specific organic molecules that specialize in replicating themselves (e.g., DNA).

We just don't know how yet - so don't give up on science...

I suspect the asker is a religious type on a fishing trip.
Anyway;; The main arguement against the big bang/evolution theory is that the odds of life evolving from random interactions are billions to one. This is true; it is virtually impossible.for complex organisms to form by chance.
However, it is also true that there are billions of stars in the universe. The experiment or gamble has been repeated billions of times. That means the probability of life occuring somewhere becomes significant.
For example, your chance of winning a lottery is 10 million to one. Yet, if you buy 1 million tickets, the chance that you will win is maybe 100 to 1. I have forgotten the formula for calculating it exactly.
The fact that we are all alive to read this means that we have all won the most extreme lottery in the universe.

The orginal earth was not 100% rocks, it was a soup contining a lot of other chemical compounds as well, like methane, sulfur dioxide, nitous oxide, carbon dioxide, water, etc.
It is this "soup" that brought various chemicals together, in the presence of energy (from lightnings and from vocanic heat). This was an experiment that was taking place at million of places simultaneously, with various recipes, and for million of years, until one of the soup recipe turned a self-reproducing simple organism. Being alone with no competion, it then took over the whole place, and various local soup condition caused the original pattern to change slightly here and there.
Once it got started, it would not stop. Change, adapt, adjust, multiply, evolve.

Created by rocks? Its made of rocks. It was created by the Big Bang which gave way to a lot of spinning, flying, molten material that accreted into the celestial objects in our solar system.

In the fossil record, the fist evidence of life is dated at about 3.8 billion years ago. The planet itself is estimated at about 4.55 billion years old. We can for the most part, trace the evolution of life from those early forms, but as to what gave to the very first initial rise to what we define as life, it is still debatable and largely a mystery.

either its God which is an answer people use because they find no alternative or somehow there was Dna and Molecules in the earth and it joind together somehow and made dinosaurs and the oceans and that jazz but the more intresting qustion is how was man created??

i would answer ur question but it would take way too long to write watch the universe on the science channel or it might be on the history channel
