If you put random amino acids in a test tube, a living organism isnt going to appear. Never mind an ocean.
Might do. That's the whole point. It's not impossible. It is possible for some amino acids to combine into polypeptides and it is possible for polypeptides to become a form of mRNA. You have to remember what random means - they could by pure chance be the right amino acids in exactly the right conditions.

Spontaneous generation has never happened. Even in miller-urey experiment where they had the wrong conditions they only got amino acids. Even if they could get amino acids in the correct conditions it would still be very far from life. I dont know much about these other experiments, but i doubt they had the correct conditions. Could you give me a good link or something?
Yes it has. The Miller-Urey experiment is just the first in a long series of experiments. Think about it, the experiment happened in 1951 - 55 years ago! Look at how far science has come since then.
They didn't necessarily have the wrong conditions in the Miller-Urey experiment either, since opinion is divided as to whether oxygen became a primary part of our atmosphere, before or after the first stages of biological evolution had occurred. Where the Miller-Urey experiment really falls down is on the fact that it does not produce all the necessary amino acids to form any sort of life, at least not on their own. The amino acids created in the experiment were all 'left handed' amino acids, the hydroxy acids and other organic compounds produced however would also be useful in the creation process. If nothing else the Miller-Urey experiment proved that organic compounds could arise through non-organic processes, which is a very important step to have taken.
Oro's experiments producing amino acids and adenine from Hydrogen Cyanide and Ammonia in an aqueous solution is probably far closer to how it really occured. Adenine is a VERY important building block for life, "one of the four nitrogenous bases that combine with a phosphate and a sugar (deoxyribose for DNA and ribose for RNA) to form the nucleotides represented by the genetic code: adenine (A), thymine (T), guanine (G), and cytosine (C). In RNA molecules, the nitrogenous base uracil (U) substitutes for thymine. Adenine is also a fundamental component of adenosine triphosphate (ATP), a molecule important in many genetic and cellular functions.". Remember G, C, T, and A, the component parts of strands of DNA, RNA and mRNA, adenine is A.
The Murchison meteorite also proved that different forms of amino acids are found in space, some of these amino acids combining with the amino acids that could quite possibly have formed on Earth could have led to the early stages of life.
There are gaps which need to be filled. But their is, in my opinion, enough data to prove that it was possible for organic chemicals to form into simple biogenetic matierials.
