Please identify a credible source where a scientist has claimed mammoths have been extinct for billions or millions of years.
Let me save you the trouble. You cannot. In fact, even the present article does not claim they have been extinct for 27,000 years. It says the particular mammoth carcass they are discussing has been dead for 27,000 years.
Is it possible that if you learned to read for comprehension, you would not be so confused?
You have identified exactly what I was riffing off of.
I figured if this poster made up numbers, I could too.
The wife and I visited the mammoth dig site in SE Wyoming two years ago. Interesting place. Apparently, it was a wallow hole for both Columbian and Woolly mammoths, but only for the boys. Of the 50 carcases or so found at the site, none are female. As I recall, the tour guide said the last mammoths roamed the earth about 12,000 years ago.
