We aren't completely sure. Here's a paper on a couple variable speed of light ideas:
Variable Speed of Light Theories
The main consequence of the first idea is that maybe the expansion of the universe isn't accelerating. In this event it would still be billions and
billions of years old, which we thought even before we determined the expansion was accelerating.
The second idea allows for a possible variation in the speed of light by 10-15%, which there's no good evidence for that I've seen, but even if that
was true, a 15% variation would not get 14 billion years down to 6000 years.
I suspect any other alternate theories would have that same problem. The difference between 14 billion years and 6000 years is just too great to
explain, plus, we have pretty good evidence the Earth is much older than 6000 years old, like tens of thousands of years of ice cores (sort of like
the polar ice version tree ring age dating). So whether the speed of light is constant is less than completely certain. But that the Earth is over
6000 years old, I don't think I'm going out on too much of a limb by stating that's fairly certain. As one scientist said, the only way the Earth
could be 6000 years old, is if God made it 6000 years ago in a way to appear billions of years old, though he wondered why God would do such a
Also, time is variable according to relativity, which is well proven. Scientists can now put one clock a meter higher than another clock and measure
the time difference. This is well supported with observational evidence, but again won't compress 14 billion years into 6000, unless perhaps you're
just outside the event horizon of a black hole, which we aren't. An observer A near the black hole might only experience 6000 years, while an outside
immortal observer B would experience 14 billion years over the same time interval, but if observer B could see Observer A's clock, they would see it
tick off 6000 years while their own clock showed the passage of 14 billion years.
