According to what the Earth itself is showing us, it is WAY older than 6000 years. The Earth can not lie about about itself.
The secular world says that the big bang occurred 14 billion years ago. Everything was compacted into one spot. It expanded, then the stars formed themselves, and then our sun formed, and in the dust around the sun, the Earth formed. It was a hot molten blob, got covered by water, and then biological evolution happened. But if that's the case, you have any number of problems. According to evolution theory, or at least atheist evolution theory, the big bang created everything, gas clouds went everywhere, and stars contracted from gas clouds out of their gravity. Well, it's impossible for gas clouds to contract out of their gravity because as soon as you get a gas cloud that compressed, it's going heat up. And hot gasses want to expand, and that expansion force is a hundred times or more than the force of gravity. It could never happen. There are all these dog ate my homework stories about how gravity waves from black holes might do a push-pull thing on gas clouds and make this actually happen. But you have a chicken and the egg problem here, because don't black holes come from stars? So you have to get stars in the first place!
There are many, many questions in science that have not been answered. But there are many questions that have been answered. So far, it is the problem for the evolutionist of the questions that have been answered, like the coalescence of the stars, like violating the first law of thermodynamics, that matter and energy cannot be created or destroyed, the big bang insists that happened at least once. Many people think the universe popped into existence instantly in a big bang, and it happened by itself! Somehow matter has spontaneously come into existence without a prior cause. The first law says that energy is neither created nor destroyed. And equally as valid as the first law is... The second law of thermodynamics, which says things are currently running down, energy is becoming less useful. The useful amount of energy is always decreasing ,and we measure this with a thing called entropy. The entropy is always increasing. It's almost as if the world was wound-up like a clock, and it's been unwinding. The second law would seem to argue...That the universe has not always existed, the material universe has not always existed. But the first law says you could not have a beginning. So, we have this contradiction. We have this tension. Both laws are equally true. And yet both laws, if extrapolated into the past, contradict each other. Physically, the universe has no natural explanation, it doesn't have a physical explanation.
Comets really do have something to say about the age of the solar system. We can divide comets into two groups. We call the short-period comets and long period comets. For short period comets, a couple hundred years, they're all gone. There shouldn't be any left. Long period comets, tens of millions or maybe a hundred million years, but they're all gone again. So for a billions of years solar system, you have a problem, thousands of years, not a problem. We understand that the sun is powered by nuclear fusion and that could power the sun for billions of years. As it produces energy like that, it changes its composition inside and over time it should slowly brighten. And as it does, the Earth would get warmer. Now again, over thousands of years, not a problem. But if go back a couple billion, three billion years or so when life first supposedly developed on the planet, you have a problem because the Earth would have been far colder. It would have been frozen, and nobody thinks that happened. In billions of years, it's a problem, thousands of years, not a problem. In fact, other planets in our solar system testify to a young universe as well. Both the density and magnetic field of Mercury cannot allow for millions of years. In 1984, Russell Humphreys correctly calculated the magnetic fields of Uranus and Neptune several years before the Voyager 2 satellite would measure them. Humphreys used a vital clue from the Bible, that the universe was made only 6,000 years ago. And when the surface of Venus was mapped in the mid-nineties, volcanoes, craters, mountains, and other features showed the history of the planet was young. Neptune is too hot to be old. Pluto still has nitrogen in its atmosphere. The rings of Saturn and Neptune aren't uniform, as they would be after millions of years.
So, do we trust in the timeline of men, who are repeatedly wrong and having to change their beliefs or do we trust in the Bible, which has never been proven wrong and does not change.
It is interesting that coal has ages from 2.6M years to over 400M years. Coal has been dated using layers in the ground, and each layer corresponds to a different part of the timeline. I found a cool link that describes how fossil age is estimated, and similar methods are used to estimate the age of coal: How do scientists date rocks and fossils?
