What do you think the world would be like? How would it change the course of history?

This is so hard to answer. One thing is for sure, there can never be a perfect answer for this question. I would say that "Life goes on". Whether chess exists or not, life goes on bro and certainly time does not stop. So obviously it wouldn't cause much of a difference to the history of this world.

There is plenty of proof. The only proof needed is logic (although weather could count as proof too). You just aren't thinking hard enough.

Your first thought is, "How can a butterfly change the weather on the other side of the world? More so, how can a butterfly change the history of the Earth?" However, the question that is more logical is, "How would a butterfly NOT change the course of the world after thousands of years have passed?"

It is obvious that a butterfly does not change the course of the world in a few days. It can not change any course of actions by flying from one spot to another immediately (except for the rare occasion, such as a driver getting distracted by the butterfly, and consequentially running into a gas station, in which explodes, killing dozens of people and causing massive damage)

I doubt that a butterfly can even change the weather after a few days have passed. However, the atoms that have been moved will change the atmosphere around it slightly. This change will spread, although a slight change. However, this slight change will make another slight change, and the change will keep spreading. The change made will keep spreading throughout the atmosphere, and will become bigger and bigger, changing slightly faster. Eventually, other courses of action will change, such as bugs, plants, and bacteria dying or living due to these slight changes. This will cause bigger changes, and this will spread changes even further. Bigger and bigger changes might occur, such as animals dying, lightning striking a good distance away from where it would have stricken, rain falling in a slightly different place. This will cause even bigger changes. This can cause the landscape to slightly change and will start having a greater probability of significantly changing at least one event significant to humans. This will cause greater change. Eventually, people will start having minor changes in their life, such as losing a baseball game or forgetting to do the bills. Weather will greatly change. Eventually, these actions will change everyday lives within a greater radius. The weather will also change, to the point in which it is completely different from what it would have been. This effect is bound to spread throughout the world eventually. People will start dying and being saved because of the effects taking place. This domino effect becomes more of a snowball effect, in which creates such great changes, it will be bound to change history. People will be born that will directly change history, for the good or the worse. People will die that would have directly changed history but instead changes history by being an absence to this world. Wars will be declared, diseases will be cured, laws will be made, companies will collapse, countries will shift their borders, split, or even fall completely. Soon enough, every single person that is alive wouldn't have been alive, because there would have been different people if it weren't for this avalanche of events that would have taken place.

Culture, politics, and country boundaries would be different. Household items, the Internet, and social media would be different. College, toilet seats, pencils, technology, global warming, and clothing would be different. None of would be alive, neither me nor you. None of us would be on this forum. President Trump wouldn't be president, as he wouldn't exist. And that's just assuming USA would exist. Nobel prizes wouldn't exist. People as we know it would be different.

But everything that we know has come to be

All because a butterfly was daring enough to flap its wings

You are right about this although you did blow this out of proportion. The IMPACT of the butterfly flapping it's wings (and other humorous things you mentioned) is "NEGLIGIBLE". Although it induces some finite change, it is still "NEGLIGIBLE" when compared to the overall scenario.

can you see the flyiing tern?  

you must look close....it is flying very fast
