No one knows it. Scientists lie or exaggerate about knowing.
Although the above is partially true, scientists do have theories about how the solar system was formed. If the entire solar system was formed at the same time then all objects in the solar system are the same age. Using radioactive dating of meteorites scientists calculate how long it has been since the meteorite solidified and go based on that date.

No. Most comets are about the same age as the solar system as they formed with it.
Because it is within the limits of our solar system
The Solar System is about 4.6 billion years old.

Age of our solar system (~4.6bya)
The approximate age of the solar system based on the oldest rocks that have been analyzed is 4.56 billion years.
The Earth is part of the Solar System, so they are of the same age.

That's the age of our Solar System, so you can expect all the planets in our Solar System to have approximately that age.
They tell us the age of the moon, which indicates when the Solar System itself was being formed.

As far as I know, this is mainly determined by radioactive dating methods. If a rock is found (for example, from a meteor) that has a certain age according to such dating methods, then it follows that the Solar System is at least as old (assuming the rock was part of the Solar System to begin with).
The solar system is believed to be 4,568 million years old.
