Recent studies have suggested that the glaciers that helped form the bridge connecting Siberia and Alaska began receding around 17,000 to 13,000 years ago...

Remind me, why did the glaciers begin receding beween 17,000 and 13,000 years ago?

Could have been the result of the Great Flood from the days of Noah.

Scientists believe that the landslide election of an early tribe of Republicans was responsible. They designed advanced bronze weapons, traded stock certificates hand-printed on birchbark and, most egregiously, invented fire, even though they had never agreed on a plan for safe long-term disposal of ashes.

Because that was around the time when what became known as White Europeans completed the genocide of the peaceful indigenous tribes inhabiting the vast forests of Southern Eurasia. Ever warlike in nature, these proto-Caucasians felled the forests for wood to fuel their wasteful lifestyles. In so doing, they created the first cycle of global warming.
