Yes testimonies are evidence. Our justice put people in jail based on this all the time. But anyway we have much more than testimonies. We have Air to Air radar, Ground to Air Radar. Metals with isotopes showing that they were not from here, documents. etc etc.

To far to get here???

This is with the physic we know only! We were using horses to travel just about 100 years ago. We know nothing yet! Just a year or two ago quantum physics experiments showed that two atoms entangled are interacting in real time no matter how far they are from each other. We have no idea how this is possible but still we now know it is real.

Poor humans always think they know everything, 1000 years ago they knew everything, 500 years ago they knew everything, 100 years ago, today, tomorrow. but still we no nothing yet. When those two brothers were working on the first plane, the newspapers were saying it would never work. We know just a bit about mass/space/time etc. we haven't been able to play with it just yet.

Maybe "Truth comes out from the children's mouth" after all:

I wouldn't put money on that wager.

Sounds interesting!

Then what are those highly trained and respectable fighter pilots seeing? Its obviously something they come in contact with.

" Fighter pilot chases UFO, urges world leaders to take the threat of aliens seriously "

An American pilot who claims to have chased an alien aircraft has warned world leaders to take UFO sightings seriously.
Retired US Navy pilot commander David Fravor spoke out in support of ex US government intelligence officer Luis Elizondo, who last week revealed he ran a real life "X Files" UFO research department at the Pentagon named the Advanced Aviation Threat Identification Program (AATIP) funded by £16 million ($22m) “black ops money” from Congress.

Commander Fravor, 53, was flying one of two fighter jets on a routine training mission about 100 miles into the Pacific ocean off San Diego when they were diverted to check out an aircraft spotted on radar from their navy cruiser the USS Princeton.

The operations operator said they had been tracking up to a dozen mystery aircraft over two weeks but hadn't had manned planes deployed when they showed up.
The object first appeared at 80,000 ft, then hurtled towards the sea, stopping at 20,000 feet and hovering before dropping out of radar.
When Commander Fravor arrived he saw a white aircraft hovering 50 feet above above a disturbance in the ocean.

He said: “It was just moving randomly around - this 40 foot long white tic tac looking thing, with no wings.
“It was a clear day with a blue background and it was perfectly white. We didn't see any windows, no form of propulsion, nothing, just a big white object.
"It was rounded on both ends and had a cylindrical body which rounded in, same front to back.
“I couldn't tell what it was made of, it was bright white but it wasn't reflecting a bunch of light."
Fravor flew towards it and the aircraft began ascending towards him, passing him at about 12,000 ft. He thinks he got within half a mile of it.
He said: “I literally chased the thing and it started to mirror us, it was like it became aware we were there. I cut across to see if I could get closer and it rapidly accelerated and disappeared. Within a matter of a second it was gone.”

Asked what was going through his mind, he said: "I was thinking 'That's pretty strange'. In 16 years of flying I had never seen anything like that. Nothing that can hover and climb at that rate up and then accelerate and just disappear.

Video shows Navy pilot’s close encounter with an unidentified fast-flying object

Here's a video remake of what happened in this specific case:

:small-smi

To make a simple contact of two messages like "Hello there. How are you?" ... "I'm fine, thanks" with aliens that live 1 billion light years away, we will need at least 2 billion of years on Earth. I don't think our civilization will be alive till that time :)

You sir, are correct sir.

But this gives me an idea. Imagine earth sends a space ship to Jupiter. A radio signal would take 43 minutes to get from the Earth to Jupiter, and another 43 minutes to get back, making real time conversations impossible, right? Imagine we put 1 satellite in earth orbit, and another satellite in Jupiter Orbit, each with a special radio. The special radio takes radio waves and uses them to vibrate / oscillate a photon that is quantum entangled with its counterpart in the other satellite, which is then read and turned back into radio waves. Since what affects 1 entangled quantum particle affects its counterpart instantly regardless of the distance, wouldn't this deliver real-time conversations?

I'm guessing this would not work for some reason I didn't consider but man I'm fascinated by the idea...

Actually these researches are being held for many-many years. Quantum Communication Just Took a Great Leap Forward

Perhaps it will work someday, but it won't help us to make a contact with the aliens that live billion of light years away.
