Such an absurd statement!
One thousand years ago, there was no Arizona!
One could just as validly claim that a greater number of homicides had been recorded than at any time since the Cretaceous Period!

Did the natives keep water records 1000 years ago.
Amazing the “scientists” know exactly how much it rained 1000 years ago and exactly what the weather will be 100 years from now but can’t predict the weather more than a week in advance.
