The Earth is very old. But how old, exactly? And how can we know with any degree of confidence? As Henry Reich describes in the video above, the process of scientifically estimating the age of the Earth revolves around, essentially, finding the oldest piece of the planet we can, then figuring out how old that piece is.
Finding super old rocks is conceptually straightforward, but practically difficult. The processes of plate tectonics mean that the Earth is constantly recycling its rock, breaking it down into magma in the interior before pumping it back up to the surface once more. But old rocks do exist, says Reich, and the oldest rock we know is a tiny piece of zircon found in western Australia.
The process of figuring out a rock's age often falls to the scientific techniques of radiometric dating, the most famous of which is radiocarbon dating. This process focuses on the ratio between the number of carbon-14 and carbon-12 isotopes in any once-living being: that ratio indicates how long it's been since that being was alive. But carbon is not the only element that can be dated—a whole host of others exist. In uranium-lead dating, for instance, the radioactive decay of uranium into lead proceeds at a reliable rate.
Based on the very old zircon rock from Australia we know that the Earth is at least 4.374 billion years old. But it could certainly be older. Scientists tend to agree that our little planet is around 4.54 billion years old—give or take a few hundred million.

In truth a measurement of Time in the specification that is being made by its public interpretation has not been developed yet. To meet the specification a price tag of about 4.8 Billion dollars would need to be paid.
However, the method of setting an educated estimation is based on several things as we are using years as a gauge for the collective history to be recorded in. To find a precise age of earth a price tag of 2.1 Trillion dollars would be required. This would include a 50% non-refundable deposit and a escrow account for the balance.
I personally do not think the average person has need for this kind of detail of Energy, Mass Mathematic Time. One in part of the price high tag. Two its only realistic use is for fast deep universe travel and navigation. In which a budget of Nonillion/Quintillion would be easily reached as the resources become endless.

You seem to be unaware of a concept known as "geomagnetic reversal." I would recommend learning more about that before you assert the non-existence of it.
I recommend (at least) reading through these sites to gain a deeper understanding of geomagnetic reversal:

Not more than 7,000 years old, you say? So it cannot be, say, 7,002 years, but can be 6,999 years? That is an interesting estimate. I assume you have a lot of evidence to support it?

If you can answer this question, then you can easily see how magnetic reversals are inevitable in virtually any enclosed system over large periods of time, and Earth is no different.

You have not responded to my question. What, in your view, is the source of magnetism? Where does magnetism comes from? What processes are responsible for it?
If you answer this question, then I will explain to you why magnetism in an enclosed system is likely to experience periodic reversals, no matter what the system is like.

This is a little odd as I quote my own mathematic understanding made as an additional law of motion. Magnetism is a translation of gravitation to energy as a 5th law of motion. The 4th law describing gravity’s motion in energy source modulation, elasticity, and reverberation.
