No rock samples have been found so far that are older than 4.2 billion years.
Maybe that says something about the age of the earth, do you suppose ??
Probably the "mare basalt's where some dated samples are as old as 4.2 billion years
4.6 billion years

Four to five billion years.
The Hadean Eon lasted from Earths formation about 4.5762 billion years ago until 4 billion years ago, some 576.2 million years.
Until it dies. 10 billion years. (:
The Earth has been a planet for approximately 4.5 billion years. It formed from the primordial solar nebula as a result of the process of planetary accretion.
One million years, in astronomical terms is a short period of time. Models of star development dates our solar system at around 5 billion years; this ties in with radioactive dating of meteorites and moon rock samples which dates them at 4.5 billion years.
The earth is estimated to be around 4 billion years old, and also is estimated to live until another 4 billion years; it is halfway through its life.
The lunar rocks brought back by the Apollo missions were estimated to be around 3.9 billion years old. These rock samples provided valuable insights into the early formation and history of the moon.
A billion years equals a billion years. 1,000,000,000 years
in about 13 billion years, that is the amount of time universe was created ago.
