Is this sign revealing rapture of the church and Second Coming?
Scripture does not state nor confirm a pre trib rapture of the church!
--------------
Is Rev 12 sign really telling us what it reveals?
I'm not a profess in making movies, nor a profess regarding scripture, but this sign is such as a clock in time warning us for the next changing of times upon the world; another period then starts; the last age of the old world ends, and what was written shall be revealed.
The Rev 12 chapter does not tell us about rapture,  but warns us from bad times coming up next. 
Therefore, do not hesitate with a thought this will last another decade or centennium, but it is now, today, and about time to wake up and be ready, for Yeshua will return after the message of the 6th trumpet has been revealed which accords and announces the 6th bowl, for at the seventh it is the END!
