The asteroid that hit the Yucatan Peninsula 65 million years ago caused both long-term climatic change and a tremendous firestorm that swept across North America  We cannot show that it was this fire that caused the extinction of the triceratops, a North American dinosaur in existence at the time of the impact of the asteroid  Nor can we show that the triceratops became extinct due to the climatic changes resulting from the asteroid' s impact
Hence, we cannot attribute the triceratops' s extinction to the asteroid' s impact
The flooding in the basement caused damage to the furnace and also caused a short in the electrical system. Fire investigators could not show that the damage to the furnace caused the fire that resulted shortly after the flooding, nor could they show that the fire was caused by the short in the electrical system. Ttherefore, we cannot claim that the flooding in the basement caused the fire.
