I have this theory. We exist, therefore they exist. If the odds were millions or even billions to one, there is that possibility there is a more advanced species out there.

After decades upon decades of the Gov saying aliens and ufos don’t exist…

They’ve announced that they’ve been studing ufos and have caught them on camera… for decades.

So they’re either lying then or now, which is it?
