Some theories about Jesus-as-an-alien or aliens-as-angels have been around since at least the early seventies. I don't believe such stuff, but this isn't the first time the two subjects have been linked.
might wanna ask a few people who have walked off gurnets in morgues what their opinions are of Jesus and where folks go when that sheet goes over their faces...
It is hard to ignore this link when there are specific references in the bible to flying unidentified craft, among other puzzling topics (such as the quote "there were giants in the world at that time")
