Frankly, it isn't impossible that UFOs could be of alien origin. We now know that there are planets orbiting many other stars and that planetary formation is actually quite common. So, there really could be life 'out there' and it could be intelligent advanced life.
Lately Senator Harry Reid has been making some pretty amazing claims. When combined with the videos Navy pilots have captured 'aliens in UFOs' becomes a far more reasonable hypothesis. Hey, we've had a global pandemic, why not alien visitation!
Common sense here folks, if these things are being called a security risk then they probably aren't ours. So, either another earthly power has developed some very highly advanced technology or *somebody* from *someplace* else is zipping around our skies with impunity. I just can't see any other possible explanations for this.
People all over the place are seeing these things...they are something that's for sure. Supposedly the Pentagon UFO Report is coming out this week...but guess what? Yep, they still don't know what they are!
