.Can someone out there please explain to me why hydrocarbons are called "fossil fuels"?.
any combustible organic material, as oil, coal, or natural gas, derived from the remains of former life.
No idea how or when the term originated. But pretty obviously it's because of the belief that they originate from the remains of plant or other (animal/bacterial) lifeforms that got trapped in geological deposits many millions of years ago in similar circumstances to those where real fossils are formed.
Equally pretty obviously the term has little or nothing to do with the normal processes where parts of a dead but once living organism get converted to stone and then capable of existing for millions of years as real fossils.
Yeah, if they're fuels they're not fossils.

Aye, thank you for that . I was extremely rushed with my comment but what I was trying to get at is that if the end result of plant/animal decomposition or whatever is methane/ethane etc then why is there humungous quantities of it OFF the planet?....

Nothing against Narrow Boat Enthusiasts just that, when "restoring" a derelict canal which nature is reclaiming, they are potentially a minority. I wonder what the reaction would be if someone proposed building a brand new canal rather than restoring an old one?
I think we're in general agreement about the subject though.
Not proven that hydrocarbons are fossil fuels. Abiogenic Hydrocarbon theory, is the idea that they are natural like many other minerals and do not come from biological origin, but rather contamination has caused the appearance that they do. When people assume they are fissil, their estimates of supply is less. In a pop physics book debunking wild theories, this chapter ended with : plausible
"Astronomers have observed that hydrocarbons occur on many planetary bodies such as meteorites, comets and in particular on Titan, a moon of Saturn. They are a common substance in the known universe. They are found in the kinds of gas clouds or nebulae that were the origin of stellar systems like our solar system. Is it [It is] reasonable to speculate that the Earth contains oil and gas for reasons that are all its own and that these other bodies had it built into them when they were formed. ... [Emphasis added.] [Of course another possibility is that some hydrocarbons were formed after these bodies were formed, and that they are still being formed. It would seem that what is going on Titan strongly raises that possibility.]
The theory that petroleum was all biological originating had become firmly established before astronomers had definitive evidence of the existence of hydrocarbons on other celestial bodies. In the whole petroleum and coal history, there exists a fact that these substances contain some biological material. However, this could be interpreted with the theory of a primordial hydrocarbon mixture to which biological products have been added. [Emphasis added.] [This biological contamination of abiotic petroleum was also contended by Professor Gold, and by the Russian and Ukrainian scientists, as noted above.]
Geochemists are used to think that hydrocarbons could not occur in the Earth's mantle which begins in depth between 7 and 70 kilometers below the Earth's surface ... . [Also, as noted above, it is not expected that fossils would be found below 16,000 feet.]
In fact, petroleum and natural gas wells are drilled 5 to 10 kilometers in depth. Recent research in high pressure thermodynamics suggest that the mantle's heat generated by radioactivity and its pressure could allow hydrocarbons to form and exist to a depth of 100 to 300 kilometers. It is claimed that the Earth's mantle could contain hydrocarbon reserves larger in magnitude than its crust."
- Methane is common on other planets and there was no life there. Oil companies like the other idea that oil is an irreplaceable fossil fuel cos it keeps oil prices high.
- The book I read was Nine Crazy Ideas in Science: A Few Might Even Be True
From 9 'crazy' ideas he found 3 could be true
In the midwestern US, the term "fossil water" is applied to extractions from wells into the Oglalla Aquifer. Obviously the originally deposited water has not been replaced by rock of the same shape -- as we use that term regarding bones, leaves, and trilobites. The term "fossil" as used for coal, oil, water, and appears to be a metastasized metaphor for ANYTHING laid down in the rocks a million or so years prior to being dug up, pumped up, extracted, examined or exploited.
As an aside, in the US Senate a few members of extraordinarily long tenure deserve the appellation, in my opinion.

AJ: perhaps it is the explanation of my own ideas that is a bit muddled; in the example you gave about being cold then warm, the facts about the particular environments did not change; one was cold, the other warm (or hot); it was just a matter of your perception – your awareness of the environment. Usually, if the air temperature is “just right”, we are not aware of the temperature; we are only become aware when we become uncomfortable.
As for heliocentricity, the facts have never changed – the Sun is, was, and will always be (as far as we are concerned) the centre of our Solar System, and the planets and associated debris will always move around it. It is the human interpretation, our various theories, of this phenomenon that has changed, not the facts.
As for a flat Earth, I thought that idea had been debunked a long time ago – it was mooted by some Victorian writer as a joke, that ancient people thought the Earth was flat. Somehow, that idea took a hold on popular imaginations, and has clung there ever since. It is known that Columbus knew the Earth was a spheroid, though a bit smaller than it is – hence his short-cut westwards to India bumped into the Americas, which he was convince was India, hence the name for native Americans being “Indians”. Odd, that, as the Piri Reis map upon which he based his adventure does quite clearly show America, so why he should misread that is anyone’s guess (it also showed Antarctica as a continent in two halves, and that was not confirmed by “science” until the 1950s – how is that explained? As usual, by ignoring it…). Even the Romans and, I believe, the Phoenicians, new the Earth was round, too, so the “Flat Earth” idea is actually quite a modern one.
As we humans are the biggest influencers upon the environments of this planet, we should take some consideration for other species; we really do not know the complex inter-relationship of many of the species, so should be more circumspect in the destruction of any one of them (except cockroaches, of course – loathe the little beggars!). You never know, there might be the cure for some terrible disease hiding in the chemistry of one of them (quinine, anyone? Or aspirin? What about penicillin? All good examples of natural solutions to old problems).
I suspect most of us have this awareness in us, whether by education, indoctrination or instinct, I cannot say, but there is little doubt that this awareness is being used for, as you so rightly state, a power-grab by people with more nefarious intent.
As for “fossil fuels”, there is crude oil now being found at levels below – like, way, way below – where rocks fossils are known to exist; in other words, the likelihood of it being from another life-form is really not very high. Indeed, the term “fossil fuel” was first used as an off-the-cuff explanation; having no other explanation for its existence, it was assumed to similar to coal in origins, with absolutely no scientific validation; to the best of my (admittedly limited) knowledge, there has been no scientific investigation as to its origins, at all. While I cannot explain the origins of crude oil or LNG, etc., all I can say is that none appear to have origins solely in life; perhaps their description as a fossil is as valid as that of Pouncer’s “fossil water”.
SandyS: please forgive me; while I may be in agreement, I often like to prod for a reaction.

Me too, I like to ask the dumb question, as it's a bad day when you don't learn something new.
P.S. As for Chandra, he is just going to have to go down his own path in his own way and at his own pace.
He knows where he stands.
He ain't no Monty anyhow.
I'll be getting on with my existence as best I can anyhow....
