We don't know. Remember that it has only been about 50 years that we have known the structure of DNA and only about 30 years that we have been able to manipulate the genome. There are still a tremendous number of things we simply don't understand yet.
When it comes to the origin of life, there are two main problems:
1) the actual evidence from 3.8-4.0 billion years ago is pretty scanty. We have fossils of early bacteria and we can see how early life developed into more complex life over time. But the evidence for how life got started is very rare because of the age of the evidence. This means that we are often limited by models.
2) Since we don't really know exactly which batch of chemicals is really needed for life, it is difficult to figure out how the necessary ones were formed and got together. We have been able to produce many of the basic building blocks of life, but our lack of information about the early earth means we are often simply speculating. However, life did not 'come from nothing'. There were many crucial chemicals on the early earth that were certainly involved in abiogenesis.

The source of life is non-living things in the presence of a high-energy environment. The nature of those non-living things is such that their low-energy state is a highly informatic state.
You can't ask a question, deny one answer for no reason, then assert that the other must be true. Until you've done some study of abiogenesis, you really have no business asking this question this way.
For the record -- life isn't a "living" or "nonliving" scenario. There is a gradual spectrum between the two, though the spectrum is HEAVILY weighted towards the ends. Where, for example, do you place a virus? Living? Nonliving? Semiliving?
Further, Evolution doesn't even care HOW life started. Evolution literally begins once the life IS started, but it doesn't try to go beyond that point. Beyond that point is the realm of physical chemistry and abiogenesis. The latter leads into the former.
In short... your ignorance is showing.
Try harder.

Viruses are both alive and dead, so there are things that are in between. Here is an article about the the current scientific debate if you want to read a little about it: http://serc.carleton.edu/microbelife/yellowstone/viruslive.html
Not being able to be exact about the mechanism does not imply magic. It only implies that there isn't enough data yet.
As to the part about god being eternal, it would be simpler to assume the Universe is eternal and you save yourself a step that there is no evidence to support. You end with the exact same conclusion-- that something was just always here in some form. Why would you complicate it with nothing to back it up?

self-replicating molecules made of organic material existed on early earth.
these molecules through chemical reactions can replicate themselves, and gradually grew more complex, much like life later in history, but without dna and all that whatnot.
Though the first self-replicating molecules could replicate themselves, they wouldnt be considered life by most people today. They could, however, develop into simple life forms such as bacteria, and then more complex forms which exist today.
The line between what is and is not life is blurred, and so its difficult to say where it exactly became life.
Gradually simple molecules grew into bigger ones, and through chemical reactions replicated. Occasionally something happens to change its structure, but it is still able to replicate by random occurrances in its environment, after a WHOLE lot of time, the molecule grows more complex and begins developing structures such as walls and other things, and slowly begins to resemble a life form
this explanation is incomplete and lacking in details because i dont know them, but i am fairly certain thats how the scientific community believes it went down

Just because we are born and die, does not mean there is a beginning and an end to everything. There is no end to the universe, who says there needs to be a beginning? Thin outside the square. I think the values that religion teaches is so important, focus on that instead of worrying about the physical and scientific side of it. We have disproved much of the bible, but the lessons that can be learnt from it is what matters.

Your answer for God's existence, poses the same paradox you are trying to pose for the beginning of life. I have attached a link to a scientific explanation, taken from a set of notes for a course at the University of Toronto in Canada that explains the theory of the origins of life. It is more bullet points that narrative, but should suffice. Certainly more evidence has been gathered for this theory than that of an all powerful, cloud dwelling, bearded humanoid (let us make man in our image) who decrees the creation of life.

Nothing just pops out of thin air by itself. All of creation has a beginning when it first was made.
Acts 17:24
The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by hands.
John 15:1-8
I am the true vine, and my Father is the gardener. 2He cuts off every branch in me that bears no fruit, while every branch that does bear fruit he prunes[a] so that it will be even more fruitful. 3You are already clean because of the word I have spoken to you. 4Remain in me, and I will remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me. I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing. 6If anyone does not remain in me, he is like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. 7If you remain in me and my words remain in you, ask whatever you wish, and it will be given you. 8This is to my Father's glory, that you bear much fruit, showing yourselves to be my disciples.
Jeremiah 18:1-10
1 This is the word that came to Jeremiah from the LORD : 2 "Go down to the potter's house, and there I will give you my message." 3 So I went down to the potter's house, and I saw him working at the wheel. 4 But the pot he was shaping from the clay was marred in his hands; so the potter formed it into another pot, shaping it as seemed best to him.
5 Then the word of the LORD came to me: 6 "O house of Israel, can I not do with you as this potter does?" declares the LORD. "Like clay in the hand of the potter, so are you in my hand, O house of Israel. 7 If at any time I announce that a nation or kingdom is to be uprooted, torn down and destroyed, 8 and if that nation I warned repents of its evil, then I will relent and not inflict on it the disaster I had planned. 9 And if at another time I announce that a nation or kingdom is to be built up and planted, 10 and if it does evil in my sight and does not obey me, then I will reconsider the good I had intended to do for it.

In as much as I was not around to see how everything came into being (and neither were you),I say, "I don't know ..... YET!" To assume that some god, my less than intellectual ancestors made up, instantaneously farted the universe into being, is absurd. Why do people need answers to unanswerable questions so badly that they rely on infantile god concepts to give them some sort of panacea?

I believe it is possibly life is "eternal" and has always existed, and always will. Is that difficult to believe? I would think that belief in an immortal god is far more "far fetched" than belief in life having been around forever. Makes sense to me.
