Languages like Persian, Arabic and Urdu tend to define existence as a possession. Interestingly, the word for "existence" is wujood ( وجود ) in all three. While in English, it is used as a verb or a quality i.e you exist.
"You have existence" or "You possess existence" are incorrect in English.
Although this could be just a coincidence, the best explanation for this is that, since the word وجود has Arabic origins, it refers to the Arab concept of existence. Most Arabs believe that existence is one of the bounties of God. Hence if God gave someone existence, existence is now that person's possession. Similarly, according to Arab beliefs, Death occurs when God takes away existence from that person.
