A dinosaur living 75 million years ago sees a dismembered leg on the floor and it smells a bit off but the dinosaur is hungry so it eats the leg. The next day the dinosaur feels sick and weakened and that caused a hunt to fail. A herbivore dinosaur that was earmarked to be eaten survives and it lays 5 eggs, 3 of them hatch and survive for more than 12 years. One of the juvenile dinosaurs dislodges a boulder and it rolls down a hill and a stone breaks off the boulder, it is then buried under sediment.
75 million years later.
The dislodged stone is exposed by erosion and a passer by thinks it looks like pastie, he later names his new dog Pastie because the name got stuck in his head. Someone hears the man calling his dog pastie and that inspires him to open a bakery. Then later the bakery is bought by another person and he turns it into a pub. He called and pub a "The bakery". Friendships are formed and relationships started and even fueds start off under the roof of the pub.
All of those events that happened in this scenario hinged on the dinosaur getting sick. If the dinosaur decided not to eat the festering leg, it would have full strength the next day and eat the herbivore. The juvenile dinosaurs would never be born because their mother was eaten before she could lay eggs, the juvenile dinosaurs were never born so one of them didn't dislodge the boulder and the stones were never exposed to human eyes. The pedestrian doesn't name his new dog pastie because he doesn't see a stone that looks like a pastie. The neighbour of the pedestrian doesn't decide to open a bakery because he isn't triggerged by hearing the pet name. The site where the pub is, is just a house and all the events that would happen in the pub, all the friendships and relationships never happened because the pub isn't there, it is just a normal home standing in its place.
The event that are triggered by the pub never happened because the pub isn't there. It isn't there because of a decision made by a dinosaur 75 million years ago.
I wonder if the whole world works like that, someone reading this blog article now does something different because of the blog and the chain reaction lasts for eternity forever changing events around the whole world.
