How did early lifeforms began?

On THIS planet (this time at least), life started as protein chains combined into amino acids; in a sort of chemical soup. For some reason, somehow a combination of amino acids, that we call DNA; started replicating itself. Over the many times, it made a few mistakes in copying itself; and the new copy either succeeded and started copying itself, or it failed and didn't. Those copies made mistakes, thus evolution.
Eventually, the DNA chains formed a membrane around itself for protection; and the earliest cell, a prokaryote was born. Cells developed organelles, and eventually some became Eukaryotes and started going multi-cellular.
Some of these were more plant-like and started producing oxygen; some cells that couldn't use the oxygen died- while others learned to use it and prospered.
And eventually, through many trials and errors some species tried it out on land, and made it. And after many more trials and errors and a few more mass extinctions- a curious primate started coming down from the trees, etc.

In the last two weeks computer models working on matter and energy combinations found in space, near suns, showed that basic life building blocks can be formed.
In fact, they can be formed very easily, almost unavoidably. It raises the idea that the critical ingredients in life are formed in space continually in almost numberless combinations.
Some found its way to the surface of the planet and eventually took hold after who knows how man failures.
There are chemically plausible explanations of life starting on earth in the primordial soup.

To began with life, as we know it, or knew it. Has to have water or H2o, the oxygen is a requirement for most forms of life. So, we have water and Oxygen then we have to add food of some sort. we know know that some forms of life live on the abstract edge of life, and in the depths of the Pacific ocean life on carbon based items that come from the earths interior in the form of volcanic refuse. This is uncommon and unique.
We don't live this way however, there are probably other forms now we know that may be unique to our form of life. We have to keep this in mind.
Life takes water, oxygen, food, and electrical stimulation or chemical to start life as we know. We now have the building blocks for life, however basic.

more and more scientist believe in a superior power including einstein. so just think about it..and what does your heart tell you? isn`t there someone that makes things happen? read the bible and you will be amazed by how many things prove the existence of God.
