he generally accepted age for the Earth and the rest of the solar system is about 4.55 billion years (plus or minus about 1%). This value is derived from several different lines of evidence.
Unfortunately, the age cannot be computed directly from material that is solely from the Earth. There is evidence that energy from the Earth's accumulation caused the surface to be molten. Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.
The oldest rocks which have been found so far (on the Earth) date to about 3.8 to 3.9 billion years ago (by several radiometric dating methods). Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years. Rocks of this age are relatively rare, however rocks that are at least 3.5 billion years in age have been found on North America, Greenland, Australia, Africa, and Asia.
While these values do not compute an age for the Earth, they do establish a lower limit (the Earth must be at least as old as any formation on it). This lower limit is at least concordant with the independently derived figure of 4.55 billion years for the Earth's actual age.
*rocks cannot tell the age of earth for they undergo rock cycles...

Evolutionists think the Earth is 4.8 billion years old. This is a gross over-exaggeration.
Creationists think the Earth is 6,000 years old. This is a gross under-exaggeration.
The truth is the Earth is estimated to be approximately 11 million years old, based on the fact that our paternal star is not the Sun, but was a Blue Supergiant having a lifespan of only 10 million years as all B-class stars have. This is a conclusion from the completion of quantum equations in 2002 that cited the heavier rare elements in the human body and on the Earth could not have been created by our tiny G-2 class star, but can only be generated by an enormous Blue Supergiant.

According to U238-Pb206 radiometric dating on meteorites and rock from Earth the age of the planet is about 4.55 billion years old.
This figure has been observed repeatedly and has been refined as radiometric dating techniques have improved.

Last I heard- it was about 4 to 5 Billion years old ( just a Twinkling in the Eye of the Universe!)...

Around 4.6 billion years old, the age of the solar system. How do we know? By radioactive dating things like meteorites and making estimates of how old the sun is.

The truth is that the Earth is about 7000 years old.Thos science geeks dont know a thing . Dont they read the bible.
