A long time question solved!
Back in high school, in my social study class, the first thing my teacher taught me about Magellan was that he is the first person to circumnavigate the globe. Then the second thing my teacher taught me about Magellan was that he died on the Philippines in a conflict with the local indigenous population. The question came to me when I think about the two things carefully. How can he circumnavigate the globe and died on the Philippine half-way around at the same time? I did not really pay attention to this question at the time as I was only concern with the correct answer to put on exams at the time
Then a while ago, I came across an article somewhere on the internet that confirms my suspicion.
Juan Sebastian Elcano, he is the answer to the question I had back in high school. He is Magellan's second-in-command. After Magellan died on the Philippiens, Elcano became the commander of Magellan's fleet. Therefore, that makes Elcano the first person to circumnavigate the globe, not Magellan.
