Because the oceans have been there a lot longer than the land. Also, all life is water based, whether it lives in water, or carries it in water tight containers of skin like us. It is reasonable to conclude that life existed in the ocean before the land.
Most life on Earth still lives in the ocean; becoming land based occurred probably as an evolutionary survival development over millions of years.

A lot of the questions have a good, solid start. However, none really give a good finish. Here is the whole picture:
We see a whole lot of fossils in the ocean that indicate the earliest life may have started in the sea.
Also, we need to look at the cells in our body. 70% of the cell content is water. We need a ton of water just to stay alive. If you look at it another way, if life evolved on the relatively dry land (aside from the lakes and streams) why would we need so much water?
Also, as mentioned before, most of the lower organisims (and I mean less evolved not less important) require water as a method of reproduction. In the grand scheme of things, a non water based reproduction system is a really late-breaking (evolutionarily speaking) item.

Simplest answer is that the earliest fossils that we have are all marine organisms. Despite what creationist will tell you, there is abundant evidence to show that life has evolved and that process is pretty well understood. Do we have all of the answers?
No. But we do understand the process. Exactly what path it took we do not know and probably will never know. All science can do is follow the evidence. And so far, all of the evidence supports the idea that life began in the seas.

Why do you believe that life originated from non-life all by itself and against all odds?
Evolutionist can only guess at this... this is un-observable.
True science is study via observation- not guesswork, which the Theory of Evolution is mostly comprised of. That and in conclusive evidence along with a good dose of faith.
Believe what you will...
Even if that means choosing to live in what you perceive as truth instead of the facts as the are.

Jill W, I hope yer being sarcastic, but the first guy is right, the aquatic ecosystem is much more conducive to supporting life forms than anything else, which is why you find so much life in the ocean.

because the first organisms had lived in the water and many people believe in evolution which is the change of an animal or plant over time that helps it adapt to a change in environment

humans themselves have a high salt content,and most of the planet is covered in water [salt water] ,if you put life in to a salt bowl or peetri dish organisms will be more in the salt than regularw water,or on land has gravity water or salt water has low to no gravity.

Because the entire planet was covered in water at that time.

I don't believe that at all. I believe in creationism, because it takes too much faith to believe in evolution.

We don't. We don't know.
But, the earliest fossils we do have appear to be like marine dwelling organisms.
