The organic matter is quickly consumed by predators, and broken down through oxidation process. None of your floating organic matter becomes fossilized. Fossilization normally requires rapid burial in sediment protecting the organic matter from decay.
God's Word describes an event that explains the billions of fossils worldwide, and marine fossils on every mountain range. (even including tropical plants and dinosaurs in Antartica. Fossil evidence helps confirm the truth of God's Word.
Yes, but how come the fossils are sorted into groups of organisms ALWAYS buried under other groups of organisms? And how come each group of organisms looks like a complete biome?
Do you know that any biome has trophic levels which form a pyramid?
Each biome has the first trophic level of producers, or autotrophs otherwise known as green, photosynthetic plants. These are always in greatest numbers, usually being ten times more plants than animals by biomass.
The first trophic level gets eaten by (normally 1/10th) as many herbivores which constitute the second trophic level or primary consumers.
This is followed by secondary consumers or carnivores/omnivores, and usually there are 1/10th as many of these around.
Finally, the last trophic level comprises the fewest in number of top predators.
And one needs all these trophic levels to maintain balance.
If one has only hares and no foxes, the hares breed and there is a population explosion, they eat all the vegetation, and die out. So God created foxes to eat the hares, to stop the hares destroying all the vegetation, and then dying a slow death of starvation. Also, old age is not nice, so most animals get eaten before thy die slowly from some lingering disability. Oh, the goodness and severity of God.
And from the lowest strata of fossils, till today, there is not a biome found which does not have organisms eating other organisms to maintain balance in the ecosystem. Long before Adam, from the ediacaran biota or first organisms, there were all these trophic levels eating one another.
