Where did organic molecules originate in early earth's history? There are only two options.
Terrestrial origins.
Extraterrestrial origins.
Which is it? And how did these molecules come to be? Is there any element of faith involved in believing that organic molecules originated through abiogenesis?

Sorry MG, but from your post it is pretty clear that you don't even know what an organic molecule is. And you are not the first religionist /creationist to show such a lack of understanding of basic high school level science on Mormon message boards.
It is really difficult to take you seriously when it is clear that don't have even a basic grasp of what you are actually saying.
An organic molecule is a molecule that is comprised completely, or in part, of both carbon and hydrogen. Methane is an organic molecule, for example.
Like many organic molecules, methane can be biogenic or non-biogenic. As a biogenic molecule, it might be a gas that is often produced by anaerobic metabolism (digestion) of organic substrates.
As a non-biogenic molecule it was found on primordial Earth (terrestrial origin). Methane is also found in abundance on many of the gas planets and their moons, and is the first organic molecule to be detected on an extrasolar planet (extraterrestrial origin).
So, the answer to your (somewhat silly) question is "both".
And - it turns out that it is possible to distinguish biogenic methane from non-biogenic methane by determining the C-13 to C-12 isotopic ratio of the carbon in the gas.
