Charlemagne- exact date unknown to 814 AD
Charlemagne, also known as Charles the Great, was the King of Franks. He was thought to be a God by his people and was worshiped like one. After he died mysteriously his body was never found; all they could find was a pile of rocks in his grave! He also supposedly died at the age of about 67, which was way past the average life expectancy (age 43) at the time, much like one of Reeves other forms, Paul Mounet. Using an advanced computer facial structure recognition system invented by the world's top scientists, his facial bone structure depicted in the painting is identical to Reeves as well as Mounet and Parmigianino. The probability of different people having the same facial structure is about 1 in 100 billion, so basically they all looked exactly the same and, statistically, are most likely the exact same person.
Parmigianino- 1503 to 1540
Parmigianino was an Italian painter from Parma. Just a coincidence that his name is similar to his city of origin, right? Yet again, WRONG. Reeves had to have known where he was going, and humored himself with his name relating to one of his many inhabitants. Only about 500 people in history have ever named themselves after their city of origin, making the name very unique. Also, he was a painter, isn't painting a form of art? All of Reeves forms are artisans, except for his first identity of Charlemagne. This can be explained, however, by the fact that he became less arrogant after his run as Charlemagne, the god king. Lastly, there is no known record of Parmigianino's grave and his facial structure matches the others.
Paul Mounet- 1847 to 1922
Mounet was an actor, just like Keanu Reeves is today. He lived to be 75 yet the life expectancy during his time was around 40 years old, yet somehow there are no actual pictures or paintings of him over the age of 50. Did he even age? During this time Mounet seems to have survived the flu influenza at a very old age, which is odd since the influenza killed 95% of the people in his community with the survivors all recorded to be in their 20s. Instead records show that he died of heart disease, a very uncommon way to die during his time (only 0.01% of the population). His body was never found and is not resting in a grave so the evidence suggests that he faked his death, quite obviously, and moved along to his new identity. As the other forms, his face is a structural match.
Keanu Reeves is a god
Along with the compelling evidence that supports the theory that Keanu Reeves is immortal and has taken on many different identities over the years including those of Paul Mounet, Parmigianino and Charlemagne, his immortality stems from his true identity; a god. The only reasonable explanation for his immortality, a god-like quality, is that he actually is a god. Coincidentally, Charlemagne was considered a god by the people he ruled over and recently Keanu Reeves tweeted that "I am god- 4real tho" for a full minute before deleting the tweet. Statistics show that people that are considered immortal have a 99.99% of being a god. Seeing as all these facts are scientifically proven correct and fully support the argument, it's finally safe to say that Keanu Reeves is a god. So what identity will he take on next?
