Did a massive comet explode over Canada 12,900 years ago, wiping out both beast and man in North America and propelling Earth back into an ice age?

Earth hit Saturn's plasmasphere, or something like that, which produced an electrical shock and heat wave, which devastated life in North America. Anode electrical discharges carved the Great Lakes at that time and the electrically pulverized rock became sand and silt in a humid atmosphere. The discharges threw large gobs of the wet sand mixture in all directions, forming the Carolina Bays, Nebraska sand dunes, Illinois and nearby "glacial" loam or till etc. The heat was great enough to melt rock, which it did as far as the U.S. southwest. All the life forms burned up to form a layer of soot. It also put enough fine dust in the stratosphere to cool the planet for centuries. It produced the other markers too, i.e. nanodiamonds, tektites, neutron radiation damage etc.
