We find organisms now that are buried in sediments, such as anoxic lake bottoms, that are not being digested by microorganisms. We don’t have to use our imagination. We just have to use our eyes.
There are fossils that have evidence of being preyed on, either by predators or scavengers. There are plenty of fossils that are disarticulated which means that they were decomposed and scavenged down to individual bones. How do you explain this?
"The body is usually exposed to air and water with a lot of oxygen, so it decomposes rapidly.The animal is likely to be fossilized only if it is buried soon after it dies (or when it is buried alive!). Even then, it is likely to decompose, because water that seeps through the sediment around it usually is rich in oxygen. Sometimes, however, the body is buried rapidly by fine mud. Water seeps through mud much more slowly than through sand, so the body does not decompose as fast. Mud often contains a lot of other organic matter as well, and that uses up oxygen faster. Some animal bodies then escape decomposition. Under just the right conditions, a delicate impression of the animal might be preserved."
That’s from the American Geosciences Institute. I think I will take their professional opinion over the opinion of a guy on the internet who has an obvious beef against standard geology.
If fossilization takes a 10’s of thousands of years, why would you expect to see a 100 or 1,000 year old fossil?
You have already said that there are rare circumstances where fossilization can occur, so I really don’t see what you are arguing against. The empirical evidence is that fossilization can occur.
