They find these giant extinct trees in New Zealand that have fallen into these pits.

and have been preserved because it's when they died.

So they were able to take the tree rings and they were able to extract out the data from the tree rings and find out that 41,500 years ago was a devastating, devastating flood on earth.

At the same time,

they find these lava fields in France called the La Champe lava fields.

And these lava fields happen to have this really unique kind of bubbling lava that they can take the air pockets inside the lava and get a snapshot of what the Earth's climate was like.

So they're combining that with these tree rings.

Yeah, they're taking these things.

This is not me.

Yes, ice cores too.

So all three.

So tree rings.

Yes, Antarctic ice cores you can, not Greenland.

So they're taking tree rings, they're taking those lava fields, they're taking these different events, and they're not saying lost civilization was destroyed then.

They're saying this is the last confirmed geomagnetic excursion in Earth's history.

So I don't think I... I think I killed that slide out of here.

Yeah.

So...

What does that mean?

Geomagnetic excursion.
