Hypotheticals are fun - you meet Satan

[surftheiop]

In this hypothetical this actually happens its not a dream/fever etc.

Ok so a being that appears to be the Biblical satan enters your room with a flash of smoke.(specifics dont matter but lets say he has a couple demons along as well so you know he is suppernatual and he does some sort of magic like turn you dog to stone.)

All he says is this one sentence

"If you worship me i will grant you complete happiness and success in life" (Dont get into technicalities of what "worship" means- this is hypothetical).

He says nothing else, whats you play ?
Would you believe his offer to be legitamate?
Would you believe him to be "God" and accept offer?
WOuld you consider that if Satan exists then rest of Bible is likely to be true?

Basicaly im asking is that if you encountered a being you were sure was Satan would this prompt you to believe in and worship God?
