4.5billions years give or take

I occasionally reference this list when I need some facts for how we know hold old the Earth is.

(bear with me I'm going somewhere with this)

One of the by-products of this is that it rules out a global flood at any point in the last 4.5 (ish) billion years.

Starting with tree rings that go back roughly 12,000 years we can infer there was no flood in that period as tree don't grow underwater.

It get's kinda complicated when you are discussing uranium deposits in calcite matrices, but the killer facts are prety straightforward certain uranium isotopes are soluble in water but the daughter elements aren't so they precipitate out.

One particular calcite deposits (in the appropriately named "Devil's Hole") has inter-woven and correlating patterns of radioactive decay gives you multiple ways to date the rock (which by the way correlate between themselves and with other independent lines of evidence), however if the rocks were at any point submerged totally this rock wouldn't have formed the way it did as submersion would have altered the ratio of the decay products in known ways that isn't seen in the rock. Becuase this process took millions of years to happen you can infer there was no global flood during that period - and this particular cave would have been flooded if the dimensions of the deluge given in the bible are to be taken seriously.

And so on.


Nice video though. :-)
