Modern geologists, based on extensive and detailed scientific evidence, consider the age of the Earth to be around 4.567 billion years. This age represents a compromise between the oldest-known terrestrial minerals – small crystals of zircon from the Jack Hills of Western Australia – and astronomers' and planetologists' determinations of the age of the solar system based in part on radiometric age dating of meteorite material and lunar samples.

Back in my science days, I heard the figure 4.5 billion being thrown around a lot.

i think it's older than i can remember :P
even geologist can't be sure
they range between 4.2 & 4.7 billion years
& the differance is huge comaping to human age
no one actually know for sure but it might be as old as the sun cause our solar system was born as one
