Do you believe we are being visited by intelligent aliens from another planet?

That Grusch guy is full of it. In his testimony, he repeatedly had chances to come forward with bombshell information about the discovery of alien life, but would always be evasive and instead talk about "non-human biologics" or claim that he had to be in a SCIF to disclose any further information. If you are going to be a whistleblower, blow the freaking whistle. You don't blow the whistle by having off the record discussions in a SCIF with some odd congress members. Say it loud so the world can hear it. "I saw a dead alien dude. He had big eyes and green skin."

What is really going on is that the US military has been using UFO sightings for years to coverup advance propulsion systems. The "men in black" who have been reported to visit people who report UFOs are just CIA/defense department spooks who try to make sure people do not have any top secret info or have recovered parts of experimental aircraft.

UFOs Could Be Secret U.S. Military Craft, Says Electromagnetic Drive Inventor

David Hambling

Roger Shawyer, inventor of the controversial EmDrive propulsion system, believes that it may be powering the craft described in the recent Pentagon report on Unexplained Aerial Phenomena.

No, that is not "most likely." You made a very obvious and 100% unjustifiable assumption - "So, even if we assume that one out of every trillion planets has intelligent life". That is a completely arbitrary assumption.

You might as well assume that the probability of intelligent life on a given planet is 1 in 10^100. With this equally arbitrary assumption the probability of there being intelligent life elsewhere in the Universe becomes infinitesimal.

Once again, obviously faulty reasoning. Without knowledge of the probability of intelligent life emerging on a planet, the 20,000 billion, billion stars that you cite does not, even to the slightest degree, suggest that there exists intelligent life elsewhere in the Universe.

moorest oversimplified it but is largely right. The Drake equation explains why.

Therefore the Earth is being visited by intelligent life forms from elsewhere in the Universe?

Is that your logic?

Completely and absolutely wrong.

Without knowledge of the probability of intelligent life emerging on a planet one cannot know the probability that there is intelligent life in the rest of the Universe.

And citing the Drake equation (which, by the way, is utterly trivial and obvious) as some kind of evidence that there is other intelligent life out there when it absolutely does not do that does not speak well to your thought processes on this topic.

This is true. Makes a case for the fact that these "Aliens" arent coming from space itself but either another dimension ir are time travelling.

So you mean to tell me in an age where almost everyone has a cell phone with a camera most places in the world, I still can't get a decent video of said UFOs and/or the extraterrestrial beings aboard the craft?

Just a possibility. But it might be because these UFOs are flown by Bigfoot. It is well established that Bigfoot has the uncanny ability to make any picture or video of him turn out to be completely blurry and inconclusive.

Yes, why is that so shocking? It takes a few seconds to pull out a phone and open the camera app and starter recording but the phenomena of interest like seemingly instantaneous deceleration and reverse acceleration are practically instantaneous.

If they wanted to be seen they'd have introduced themselves already.

If they don't I'd wager a species capable of interstellar travel could figure out how to avoid being seen by a bunch of apes.

It's really hard for most of us to appreciate the distances that need to be traveled. Even though Voyager 1 was launched in 1977 and travels around 1 million miles each day (insane!) with a speed of around 38k mph, it took 35 years for it to enter interstellar space. It's going to take another 300 years for it to reach the Oort Cloud and another 30,000 years just to cross it... let that sink in. If we could travel at light speed, we could cover 16 billion miles in 1 day, but that just gets us past the Kuiper Belt. It would take another 29 days of travel at light speed to get to the Oort Cloud. The nearest star with planets is more than 4 light years away. I'll let you do the math and estimate how long it would take Voyager 1 to travel that distance.

And this is just talking about getting to the next solar system. All the others are much further away and our galaxy is 100,000 light years across. What I'm getting at is that light speed isn't sufficient. This is why most sci-fi books just go the portal/space jump route. So for you to believe that aliens are visiting us in crafts, you have to believe they found us somehow and figured out how to jump vast distances to get here.

Even if another solar system has the conditions for intelligent life capable of this kind of tech/magic, time is another factor that must be considered. The universe is supposed to be 13.7 billion years old. The conditions for intelligent life in another solar system need to be right at the same time that it has happened to us.

I believe there is intelligent life out there due to the mind boggling estimated 2 trillion galaxies in the universe. But due the distances and travel contraints, the odds of one identifying another are just too low.

This UFO stuff is pure fantasy...

No aliens have ever been here. They read the reviews and we only have 1 star.

The 13.7 billion year theory just got dropped recently. They're now saying it's close to double that.

Given what humanity has managed to accomplish in just a few thousand years it's silly to put a limit on what some other civilization that could be a billion years old has accomplished.

A very old civilization could very well be fully integrated with machines and be immortal so traveling thousands of years isn't an issue.

But then who created them?

As of right now, based on the science we have, the probability is 0. 1 in 700 quintillion is a very high probability and all science suggests it is 0

If they are intelligent they will never come.

Science understands a lot less than you think.
