What do you think?

I think... I know... there is a bunch of UFO's literally attacking us right now. I wouldn't surprise me if they attack area 51 and cause an earthquake. Earthquakes are not good when it comes to underground / mountian facilities. Earthquakes is just one thing we can expect from these bastards. I expect them to play with water soon and cause some major water damage. I expect them to start giving us humans and farm animals diseases that we can't figure out. They will zap the crops across the globe to cause crop failures on an unprecedented scale. The effects of the radiation they project to harm, not only kills, but worse is make humans go crazy before they die, odd behaviors and stories will be prevalent.
Brazil is currently under siege from UFO's Great vids on twitter, reddit right now, some of the best UFO footage I've seen. Its happening now! Search " ovni mage". Apparently a UFO has also crashed in brazil a few days ago. They are freaking in Brazil and its going viral.
