It is true that life COULD have come from space, but it's not necessary.
All of the building blocks of life can be found right here on earth.

Yes. There are two types of amino acids - L and D (for left and right). The only form of amino acids that are seen in living things are L amino acids.
Analysis of debris from outer space that has struck the earth have traces of L Amino Acids. These could have over millions of years turned into "living" organisms.
A way to look at it I guess is like "pollenation" from space.

I think you are referring to the concept of "panspermia." Apparently there is some validity to it - some scientists feel the ingredients for life were brought to Earth by colliding comets, and may explain the relatively fast development of life on this planet shortly after the "heavy bombardment?" period in early Earth's history.

yes, its called the extraterrestrail theory. There is a theory that non-organic materials were brought to Earth, by meteorites. There have been traces of the basic elements of life on meteorites. So it is a valid theory.
