Around 14B ya based on our time measurement. Time is relative you know. If something seems to defy common sense, maybe one should be skeptical .... like warming causing cooling.

Mammoths & AGW: 2 examples where common sense should prompt skepticism A study just came out saying the EXTINCTION (human-caused probably) OF THE MAMMOTHS WARMED the earth - cause without mammoths there was a lot more vegetation around: agu.org Man-made global warming started with ancient hunters AGU Release No. 10–15 30 June 2010 A new study, accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union (AGU), argues that this die-off had the side effect of heating up the planet. “A lot of people still think that people are unable to affect the climate even now, even when there are more than 6 billion people,” says the lead author of the study, Chris Doughty of the Carnegie Institution for Science in Stanford, California. The new results, however, “show that even when we had populations orders of magnitude smaller than we do now, we still had a big impact.” In the new study, Doughty, Adam Wolf, and Chris Field—all at Carnegie Institution for Science—propose a scenario to explain how hunters could have triggered global warming. .... Now obviously common sense would cause one to be skeptical of this. But the gullible will say: 'This is science, baby, peer-reviewed and published. Gotta believe it or you're a flat-earther.' But there's more! It seems not so long ago there was another study which concluded the EXTINCTION OF THE MAMMOTHS COOLED the earth - cause those big beasts were methane producers: content.usatoday.com Mammoth extinction triggered climate cooling Extinction of mammoths, camels, giant sloths and other large mammals in the New World may have cooled the global climate about 11,500 years ago, suggest paleobiologists. The culprit? Less of the greenhouse gas, methane, emitted by the massive herbivores. ..... So which is it - did mammoth extinction produce global cooling or global warming? Both claims are based on peer-reviewed published scientific studies.
