All we really need to know is what Our Blessed Lord Jesus Christ said about this kind of thing.
*Matthew 24: As he sat on the Mount of Olives, the disciples came to him privately, saying, “Tell us, when will this be, and what will be the sign of your coming and of the close of the age?”  And Jesus answered them, "Take heed that no one leads you astray.  For many will come in my name, saying,
I am the Christ,' and they will lead many astray.... Then if any one says to you,Lo, here is the Christ!’ or
There he is!' do not believe it.  For false Christs and false prophets will arise and show great signs and wonders, so as to lead astray, if possible, even the elect.  Lo, I have told you beforehand.  So, if they say to you,Lo, he is in the wilderness,’ do not go out; if they say,
Lo, he is in the inner rooms,' do not believe it.  For as the lightning comes from the east and shines as far as the west, so will be the coming of the Son of man.***" And then from Luke 21 we see...***" And he said, "Take heed that you are not led astray; for many will come in my name, saying,I am he!’ and,
The time is at hand!' Do not go after them. "*** and again in Mark ***13: "And Jesus began to say to them, "Take heed that no one leads you astray.  Many will come in my name, saying,I am he!’ and they will lead many astray. "…" And then if any one says to you,
****[FONT=Georgia]Look[/FONT]****, here is the Christ!' orLook, there he is!’ do not believe it.  False Christs and false prophets will arise and show signs and wonders, to lead astray, if possible, the elect.  But take heed; I have told you all things beforehand. "
