Dear Josepp - on Shakespeare, please try reading a little more widely (and not websites about pet theories). The man we know something about (if not as much as we'd like) was more than capable of writing the plays we now have, and didn't hold "ordinary" jobs, unless you think that the theatre is an ordinary job. Read Bill Bryson's excellent summary of the arguments against Shakespeare being the author of the plays and just why none of them hold much water. Read some of the very good accounts of Shakespeare's life and times. Remember that there are indeed people of extraordinary talent in every age and place. Why is it so hard to believe that Shakespeare was one of them?
As to the queens/Mary/Elizabeth - are you saying there were no historic queens of those names, or that the Bible was altered? Because otherwise I don't understand the point you're making. And clearly we have numerous historical sources to tell us that there were indeed half sisters, daughters of Henry VIII, who took their turns on the throne of England and whose names were Mary and Elizabeth - but it's also clear that there were many people named Mary and Elizabeth because of the Biblical associations of those names, so that's hardly surprising.
It seems to me you're looking for mysteries and coincidences where none exist, and I wonder why life isn't already rich and strange enough for you ... but that's another question, isn't it?
