Did Anastasia Romanov survive

There were theories and allegations and thoughts but all are wrong; She died at the age of 17 years and 27 days the whole family died in the year of 1918.

these are a few theories and thoughts

A Theory: They were taken into a basement and executed but it is said when either her or her brother was shot that the bullet bounced off some of the jewels on his/her outfit and survived. A woman once came forward saying she was Anastasia but was proved to not be.

Another theory: They whole family, except Anastasia, was taken to Siberia where they were killed. Anastasia had not been with the family for some reason when they were captured. Anastasia then grew up in places such as St. Petersburg, Paris, London etc.

A Third theory: The whole thing was staged, the family was secretly moved to New York City where they lived the rest of their lives in quiet solitude in a secret bunker beneath Central Park occasionally venturing to the surface dressed as everyday people to enjoy the city sights.

A Thought: There must be something to the Anastasia legend else it wouldn't exist. But who knows the truth? Maybe the explanation is as simple as this: Anastasia died or was killed someplace else and so the rumors started when Word spread that all the royal family was executed except her at a certain location since she died or was killed elsewhere.

A second Thought: A popular television program did a documentary show in which they claimed they had verified the DNA of all of the royal family including Anastasia in the execution location. If this is true then she did die with the rest of her family and the story is just myth.

A third Thought: A book was written called Dreaming Anastasia. In the book Anastasia escaped by being taken away by Baba Yaga, and staying for centuries in her hidden hut.
