Let me tell you a little story.  It didn’t happen this way, but if aliens arrived, it probably would’ve.  The year was 0-ish AD. The place: Bethlehem. The event: The birth of Christ.

A glowing saucer descended over Bethlehem where an odd star led them.  The shepherds, already having quite the night between angels and a miraculous birth, now stared slack-jawed as a hatch hissed open. Out stepped a delegation of aliens—tall, shimmering, and looking confused.

Alien Commander: “Take us to your leader.”
Confused Shepherd: “We were just visiting him.  He’s that way—”

And that’s how the aliens wound up kneeling beside the livestock, presenting the Son of God with interstellar worship.
