Chixchulub was not Alone: A new theory concerning the Death of the Dinosaurs and other Mass Extincti

Was there only one cometary or meteoric impact that apparently caused the death of the Dinosaurs?I will not go straight to the point but present my own geological and cosmological arguments that I have proposed to support my discovery. We start with mysteries from the dawn of time. Intermingled with cataclysms. You may be the judge of the mysteries as they weave their path through the Earth's history. Observe first and then judge. This planet of ours has had more changes and mysteries than you would ever think possible. Has human civilization been like all of the legends of the ancient ones, namely created and then destroyed and then created and destroyed over and over and over ad infinitum?
