Firstly I have seen heaps of documentaries about UFOs including many reports. I think the best evidence I've seen was on "14/03/1997 Phoenix Lights in UFO Coverup Documentary - Out Of The Blue" due to number of witnesses.
Sadly not even one evidence convinced me fully. For example of Phoenix Lights, why would UFO need those lights? so other UFO can see em while they travel light years distance? lol
I've also seen military, pilot UFO reports, e.g. UFOs disarming missile etc, cos i guess aliens were worried we might shoot missiles to their planet. hehe. Pilots racing with UFOs etc but lose cos UFOs use super NOS, Fast n Furious 5?
Lets says UFOs do visit Earth in regular bases. Aliens obviously don't want us to see em since we NEVER got any decent photo/video of em.
For example if they wanted to communicate with us or have message for all of us, I'm sure they could even use the technology we have to pass the message to everyone. (i.e. TV, internet, etc)
So its clear that they don't have any message for us, more like they don't want us to found out that they exist for one reason or another. (IF they existed)
Yet we have thousands of witnesses n reports, so how does that makes sense?
Really doesnt make sense to me, if Aliens come to Earth, there must be valid reason. If they don't want us to know they exist, we wouldnt have any UFO witnesses/reports.
I think UFOs reports are made up just like religion. There has been many Alien/UFO hoax.
Alien Autopsy video is a good example, many people thought it was real, especially those who believed in Aliens and UFOs. But it was fake.
Same people probably also think Alien Interview video is real, but it looks fake to me.
