Actually, there’s evidence in all those fields that show that long timelines are either not necessary or contradictory to observation.
Light from a star 100,000 light years away isn't evidence that the universe is only a few thousand years old.
DNA analysis shows overwhelming evidence for the common descent of species.
The evidence of the fossil record is not compatible with all species being alive contemporaneously.
Etc, etc.
But an a priori and emotional investment to useless creationism makes one unable to accept any evidence that contradicts. So, like the authors of this thread, one must allege a conspiracy theory to explain away the evidence.
