Scientists don't have an answer for this question yet. But there are hypotheses that a simple self replicating molecule arose in the primeaval soup of the ancient earth probably by sheer chance, in the likelihood of around 1 in a billion. Of course sheer luck isn't a very good explanation, since 1 in a billion is astronomically small, but consider the number of planets in the entire universe that has conditions similar to earth. An estimate puts it at about 10 billion. Since we have a sample size of 10 billion, we can almost expect for life to arise on one of the planets. Since we are here thinking about it, that planet must've been earth.

How does ozone in the stratosphere affect life on the Earth's surface?
The ozone in stratosphere affects the life on earth. It protects and shields the surface of earth.
What rocks originate from the surface of the earth?
Sedimentary rocks form on the Earth's crust, and can form metamorphic rocks when buried. Igneous rocks form under the surface, or when liquid magma reaches the surface as lava.
Are there any organism on earth that can support the theory that life did not originate on earth?
Not at present. All life on Earth appears to have evolved here, and it's all related.
Might life which does not originate from planet Earth also have developed on other planets?
Life which does not originate from planet Earth may very well have developed on other planets. There is really no other explanation for where it would have come from.
What is biogrochemisty?
Life permeates the surface of the earth. It hugely infuences the surface of the land.
How does an earthquake originate?
When the Lithosphere plates move, the surface of the earth vibrates. These vibrations can travel all around theearth. These vibrations are called Earth Quake.
