You have some factual errors in your post.
The halflife of Carbon-14 is 5730 years.
All previously organic fossils *should* have carbon-14 in them, but it should dimish with time. If you have any direct examples of old (dated through indirect means) fossil measurements that has unreasonable large amounts of C-14, then there is indeed a problem.
But even after 100k years, you should still have about 5 millionths left. If this constitutes 'nothing' is not for me to say, though.
