I don't know how many of our own would be interested, truthfully. A lot of us were there on the actual Crash Day and we know full well that this charade is ridiculous.
But the tourists would surely love to be made to look like aliens, and I'm sure you could come up with an alien-based explanation for how your magic works. Maybe one of the aliens in the crash granted you a gift? Or granted it to your mother who passed it on to you? Something like that.
