Wat is de Geologische Tijd?

It is difficult for a human being, so new to this world and so futile in his existence, to imagine the enormous expanse of time that has already passed since the Earth formed. Read a bit more about it, to get a glimpse of what Geological Time really is.

Since time immemorial. A saying often used. I abuse it all the time. It means, more or less, for as long as people can remember. With 'since time immemorial', I feel taken back to Antiquity, at least two thousand years ago and even further back to times when humans started to be able to pass on their memories and information. A quick Wikipedia search tells me that writing systems were established about 6000 years ago. Well, compared to the age of the Earth, that is peanuts, a blink of an eye, the very last second of a lifetime. 

An incredibly long time already passed before humans even existed. All 'modern' developments of humans happened during the last ten thousand years (roughly), which is known as the Holocene Epoch. The Holocene started after the last Ice Age, when humans slowly became who they are today. 

Geological time is the entire timespan since the Earth was formed. That is 4,54 billion years ago. A very long time indeed: a bit less than one third of the time since the Big Bang. It is difficult for a human being, so new to this world and so futile in his existence, to imagine this enormous expanse of time. 

Scientists have divided geological time in parts, with a few very large divisions and many subdivisions. Each subdivision is separated from the previous one, because something remarkable happened.
