Yes it can... what makes you say Carbon 14 cant exist you're no scientist.
While it was long believed that soft tissues always decayed or were replaced by minerals during fossilization, scientists have discovered original organic materials—like blood vessels, proteins (collagen), and even cells—in fossils dating back tens or even hundreds of millions of years.Here is how researchers explain the survival of this ancient tissue:The "Iron Shield" Effect: Iron from the animal's degraded hemoglobin or other bodily fluids may act similarly to formaldehyde, causing proteins to become "cross-linked" or highly tangled. This makes the tissue highly resistant to decay and bacterial breakdown.Dense Mineralization: Thick, highly mineralized bone can encase and protect soft organic matter from environmental hazards like water, oxygen, and microbes.Favorable Burial Environments: Burial in fine-grained sediments (like sandstone) and remaining meters below ground in undisturbed, uncracked fossil beds are crucial to long-term preservation.Researchers continue to study these spectacular cellular finds.
You have carbon 14 in your body and it never really goes away not for millions upon billions of years.
