They say there are 6 other people out there, who look jus like us, with slightest difference in features. This is when the term doppelgänger comes to play. It's a german word which simply means an apparition or double of a living person. So this proves that only looks of few people can be identical. But have you ever heard of the term PARALLEL UNIVERSE or PARALLEL LIFE ?
Few theories released by scientists say that our universe is another version of some other universe. Maybe this other universes exist parallel to our universe. They believe that there are other versions of ourselves in some other universe and our lives are similar to their lives . This concept is called parallel life.
The concept of parallel universe can be explained by taking examples of possibilities for an events to take place. Like, if we roll a dice, there is a probability for six outcomes.
Similarly, according to QUILTED MULTIVERSE theory, Space is infinite and in this huge space, occurance of several other similar universes is possible.
Another intriguing theory is that time is flat and it goes on forever so it is possible that many universes exist.
One of the most known example for parallel life is the similarities between the lives of former U.S. Presidents Abraham Lincoln and John F. Kennedy.
A lot of coincidences were discovered in these two President's histories:
-Both the presidents had 7 letters in the last names.
-Both the assassin's full names have 15 letters.
-Both the presidents were shot dead in head.
-They were both assassinated on Friday.
-Both the presidents had their wives next to them when killed.
-Both presidents fathered four children, and one of their son died during their presidency.
-Both presidents were elected to the House of Representatives in '46.
-The doctors who provided aid to the presidents were both named charles.
-During the assassination, they were sitting in an alphabetical pattern. Their spouses first name and both president's last name. J,K,L,M- Jackie, Kennedy, Lincoln, Mary. Jackie was seated to the left of Kennedy and Mary to the right of Lincoln.
Though the concepts of parallel life and parallel universe are intriguing, these have no definite proofs and can not be perceived.
