I see little to no discussion about alien abductions on this sub.

So let's say that you read about some stories of UFO's. Some of them are very credible, and report objects that seem to defy the laws of physics. Like a cube encased in a translucent ball flying at supersonic speeds and making sharp turns, instantaneous acceleration etc.

Or cigar shaped objects that are seen on radar and groups of credible observes (pilots, copilots etc). Often with government reports and radar data public.

Now if you go with the alien hypothesis that implies that they are flying around but want to keep a low profile and do not provide irrefutable proof of their presence.

Wouldn't it make sense that if this was the case, they would come down and pick up some humans, animals and ground samples every once in a while to have a closer look? Do brain scans, possibly test how they react to their presence, or to figure out how to communicate with us (if they are very different).

Or what I am saying is, if you make the leap that possibly we are not alone, and we are being observed, the alien abduction phenomena suddenly seems a lot less far fetched?
