How old is the Earth?

[Anomalocaris]

In the 21st century an adult presumably having access to a real education could not get much more yokelish than believing the earth the earth to be less 12,000 years old, unless he was to also believe a ship once preserved all the animals liable to drown in a world wide flood, or that world was made by a bronze age beduin sky god in 7 of some sort of days. There is nothing ad hominem about calling such a yokel a yokel, nor calling him a troll when he trolls.

Present your presuppositions and conclusions about the age of the earth first to suggest your good "faith", or shut up.
