Theoretical Question About ETs, To Whom Would You Listen?

Here's the theoretical question:

For the sake of argument, let's say four different groups of ETs land and make themselves known.

One group of ETs say "Jesus was a hybrid, he was our creation and here's how we did it..."

Another group of ETs simply say "Jesus didn't exist."

Another group of ETs say "We're the progenitors of human beings."

Another group of ETs say "Jesus was who he said he was, and 'Judgement Day' will begin on 21 December 2012".


Which group of aliens would you believe and why?

If aliens landed Jesus would be one of the last things on my mind. Some dude who lived 2000 years ago and who has been misrepresented by 2 millenniums of lies and deceit kind of becomes irrelevant if alien creatures land.

I wouldn't trust any of them as with confrontation comes lies and deceit.

However, the original ET group is offering to reveal some form of proof and evidence so I would be intrigued as to where it went.
