We'll have to wait until we can discern this from their behavior or words or both, but it would certainly fit with the Biblical worldview, which frankly has shown itself to be accurate over a very long period of time.
What’s interesting is my dad told me this like 50-ish years ago or so. I’m 57 now. I thought of it recently watching a Christian pod-cast called Into the Multiverse. They were discussing UFOs and firmly believe, based on their own beliefs and research being they are quantum physicists (very, smart in other words) there is no possibility these “things” came from anywhere other than (a) earth or (b) another dimension. The show can be a bit out there, but these are truly Christians who also discuss scripture (sometimes heavily) while talking about these issues. Show is addictive, so I warn you if you start watching you’ll probably be hooked. :)
