[Origin]

Strangely his element 115 now exist on the periotic table ... Its so rare they don't know its properties and it decays fast. But who knows?

Looks like we do know.

I would point out the 2 videos released by the Pentagon which shows a giant chicklet shape craft moving at incredible speeds and a spinning top like objected also traveling at incredible speeds.Followed by a US government statement that UFOs are a real and serious risk to national security.All the servicemen on the Nimitz.If these are alien crafts then it suggests that there is a near by alien civilization possible more than one.
On top of that I would bet everything I have that not just one species but many are out there.

One could consider that the military are working on new classified technology that they do not, at this stage want to lay claim to and that "alien technology" is a nice side track tactic. Conspiracy theory, yes I know and actually not my own personal humble opinion. Though they remain unidentified (UAP's) as its called these days, there is also no reason to believe that they are alien either. 
Anything supporting alien visitations is totally speculative, even if you imply known plausible theories based on well understood theoretical or verified mainstream science as your base for argument.

If we want to speculate based on what we currently know and our own current experiences of life on Earth, then though the likelihood of life existing elsewhere seems highly probably. What is clear is that biological life as we know it, in the least highly complex intelligent life is very vulnerable to environmental influences, time constricted and any form of space travel presents a multitude of problems to overcome. If aliens resemble any form of biological life like here on Earth, then they are also likely to face the same issues.
 
I would therefore speculate that, unless they have discovered a way to bend spacetime to reduce distances then most technological intelligence motivated to travel across the stars is likely to use highly advanced A.I systems designed specifically for purpose.

So based on this premise if those sightings are indeed of alien origin, I would speculate that they are likely to be probes of some sort, rather than vessels containing "little green/grey men"

No amount of "AI" can bend the laws of physics. On side issue, I do not believe "AI" has been achieved or ever will be. A computer has no motivation to do anything and relies solely on it's programming to perform it's functions.

How can you be sure?
Bend the laws of physics is not required! You can in theory bend space time provided you have enough energy to do so this is not outside mainstream science. I agree, achieving this seems most implausible to us based on our current technology and understanding.
However an advance technological system/species/ A.I that is far older than us may have the technology to do so. They may have also discovered further laws/understanding at a far more fundamental level than we have yet probed. You are assuming human technology, human emotion and human motivation.

AI is a system built by humans, using the known laws of physics.

And? Are you implying that all potential A.I in the observable universe is originates from the Earth?

Why would an alien intelligence not create their own A.I?
