The short answer is that we don't know. In a famous experiment back in the 50's, Urey ran an electric discharge through a mixture of carbon dioxide, water vapor, and methane, all believed to have been components of the earth's atmosphere shortly after it was formed. Various amino acids and other organics resulted. The early earth's ocean was subject to intense tidal stirring (can you imagine a tide 250 feet high?) because the moon was much closer to the earth than it is now. Given a world-size laboratory, and an arbitrarily large amount of time, who knows what might have happened? But it must have happened fairly soon, because traces of life have been found in rocks as much as four billion years old.

Your language has residual creationism in it. This may not be your intent. If you do have an agenda perhaps you should state it.
I have been burn't a few times too many by creationists that bear false witness.
I just don't think your question belongs here (biology). As a scientist evolution is not a belief; it is a working hypothisis. The idea also in your question that 'life starts' is also a belief. There aree many arguaments as to when life should be considered to start. Usually it is considered to be when it fullfills certain criteria. Ie it can replicate itself. The evolutionary chain of events is often purported to have starterd from some kind of chemical that could replicate itself given certain resources. From there selection took over. The initial replicator could have been anything really, and may not in common sense be regarded as alive.

Think of viruses. Not much more than DNA/RNA information wrapped in a protein coat. It is surmised that at first all was replicators and the biological molecules they " found "useful ". Their are even two or three theories about prebiotic crystal-type replication, that organic life imitated. I am sure that a few functional biologist can fill in this rough sketch.

It is impossible to be recreated in a lab when trying, so how could it possibly happen by accident. The only logical answer is that we are not here by accident but those that do not want to believe that will never acknowledge that fact and look for any answer besides the truth.

Recent evidence points to volcanic activity and bacteria found near the ocean floor next to riffs in the earths crust. It is believed that anything nearer to the surface would have been bombarded by radiation due to lack of an ozone layer at the time. Watch nature and Nova they have fascinating stories of bacteria they found far below. Also there is recent findings of bacteria in water they found in deep mines. I watch too much PBS. :-P

I think it was in the ocean or something. I don't know the latitude and longitude or whatnot, but I think like on land was another million years after life in the water.

Many evolutionists don't know their a s s from a hole in the ground.
