What mostly likely happened to the Lost Colony of Roanoke Island?

There are a lot of theories on what happened to the colonists of Roanoke, but some of the most popular are that

The colonists moved (or attempted to move) to the nearby island of Croatoan but perished. This is supported by The Dare Stones, which were three stones found on this island that were supposedly carve by Eleanor Dare, the daughter of John White (the colony's mayor). However, new evidence suggests that the Dare stones may have been created far more recently and therefore makes them insubstantial evidence for this theory. One piece of evidence that still holds up for this theory is that the word "Croatoan" was found carved into a tree on Roanoke Island when the settlement was found missing. The colonists were killed by Native Americans. The colonists joined the Native Americans (this is unlikely, but is still a theory). There was a tribe near Roanoke, the Hatteras tribe, and it is possible the settlers joined the Native tribe out of desperation.
