If you are a believer in what the bible says, which I know some here are...
What people need to keep in mind IMO, and remember, is whatever Gods plan is, is what will happen. Worrying about it will not change anything. The bible tells how to live, IMO that is what Christians should be doing.
In regards to the future and prophecies people like to dwell on, because they can be sensational:
"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father."
Matthew 24:36
The below link I found fitting.
Matthew 24:23-26 (KJV)
23 Then if any man shall say unto you, Lo, here is Christ, or there; believe it not.
24 For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
25 Behold, I have told you before.
26 Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not.
Notice that the term is 'false Christs', PLURAL. This means we are not looking for a singular occurance here, but several. The great deception is Christians being led away by ANY of them.

Whether someone appears today or tomorrow as a person, a spirit, an alien, who knows, think about what would be easily accepted...maybe they come and offer some energy source, or world peace for a time. As the bible says they will not be God.
