The real question is how could it not be?
Dating techniques in science do not indicate the age of anything. All they do is promote the possibility that they could still be evident in the theories of evolution, nothing more, nothing less.
For example, when something is dated, it could be anywhere from 300 years to millions of years. It could be something a day old, or something ancient, and to the same conclusiveness.
Fossils and such are re-dated until they come back with a satisfactory age, which deems a possibility.
This isn't a secret, it just happens to be left out when these techniques are explained. More modern dating techniques are simply variants of older ones, in which they conclude an age of something in relevance to their general hypothesis.
Actually, biblical events more than suffice for fossil fuels, giant 'caveman' fossils, etc., A flood would have made enough pressure to rapidly produce the fuels we use today. There are giant humans in the bible, which we see bones of. It goes on and on.
