Elon Musk, the world's richest person, on Friday said that he is "an alien" after he was asked by the founder of Cred, Kunal Shah, that how he manages to keep up with the immense workload. In a couple of tweets, Shah said the SpaceX and Tesla CEO can end up running more than four 500 billion companies "simultaneously at a relatively young age."

Shah further wrote on Twitter that he wants to understand how Musk does it? "How does he manage context switching? How does he (Musk) design his Org?" the CRED founder asked, saying he has so many questions. 

In another tweet, he tagged the billionaire, writing: " answer if you see this, dark lord."

Shah's used the Harry Potter reference in his tweet, addressing Musk as the 'Dark Lord,' which is used for the central character of Lord Voldemort of the movie series.  

To this, after hours, the 49-year-old billionaire replied, saying, "I'm an alien." 

To Musk's tweet, Shah replied: "Entropy confirmed."
