There is a lot more randomness in the universe than we realize. Its common to be "fooled by randomness" as our minds seek to see patterns and connections that do not in reality exist.

We want to believe one exists. Statistically we can’t make that leap, however. Charts that show a close correlation are often relying on a visual parlor trick to imply a relationship. Tyler Vigen, a JD student at Harvard Law School and the author of Spurious Correlations, http://www.tylervigen.com/ has made sport of this on his website, which charts farcical correlations—for example, between U.S. per capita margarine consumption and the divorce rate in Maine. http://www.tylervigen.com/view_correlation?id=1703" It can be quite a challenge to establish causality, even for "obvious" correlated phenomenon such as global warming whereby heatwaves seems to be a natural and logical result of global climate change. However, the causal link between global warming and specific extreme weather events has only recently been established, despite extensive climate studies and modeling by top scientists over the past decades. https://www.theguardian.com/environment/2018/jul/27/heatwave-made-more-than-twice-as-likely-by-climate-change-scientists-find https://www.theguardian.com/environment/2018/jul/27/heatwave-made-more-than-twice-as-likely-by-climate-change-scientists-find "Fingerprints of global warming clear, they say, after comparing northern Europe’s scorching summer with records and computer models" https://www.skepticalscience.com/heatwaves-past-global-warming-climate-change.htm https://www.skepticalscience.com/heatwaves-past-global-warming-climate-change.htm "the growing risk from heatwaves is ignored by some who argue that heatwaves have happened in the past, hence current heatwaves must be natural. This line of argument is logically flawed, using a logical fallacy called a non sequitor (Latin for 'it does not follow'). This is a fallacy where your starting statement does not lead to your conclusion. For example, this is like arguing that people have died of cancer long before cigarettes were invented, hence smoking can't cause cancer."
