Maybe there is a reason and we don't know what it is. We know almost nothing about the subject. We do know that the combination of circumstances required for life is uncommon, but we don't know how uncommon. Maybe the chance of life on a planet is one in a million and there are millions of billions of planets with life on. Maybe the chance of life on a planet is 1/9.784x10^100 and it's a freak of chance that there's even 1 planet with life on it. Maybe the universe is infinite and therefore the number of planets with life on them is infinite regardless of the chance of life.
Are we not far away from discovering alien life

It was. Otherwise it would be ground breaking news.
And like I replied to him earlier, Religious nutters will accept life from other planets and say that their God made them. The Pope even got his head Astronomer to talk about Aliens - perhaps they know something
And if intelligent aliens appear in our skies, I'll tell everyone it's my people come to take me home. Doesn't make it so. Or does it...?
Point is, what I said has nothing to do with what religious people, nutters or otherwise, believe it signifies, I'm attacking the claim that it will or could be kept secret from the general population. Unless the origin point of this knowledge being gained is politicians or intelligence agencies as the primary discoverers of alien life (highly unlikely), then it will come through public channels such as astronomers and other scientists and peer review. I.e. if it happens, we will know.
And if it does, I would like to be the first to say:
That is their argument, though - that you can't prove it. You've been saying things like it's certainty that there is life out there. And I agree that based on what we know it seems highly likely and actually improbable that there wouldn't be. But neither of us can prove it.
Quite interesting.
I'm not sure you can blame opposition to nuclear tech for it though. The plan was to put 54,000 tons of material into orbit for construction. At today's price of about $25,000/kg, taxiing the material into space just to start construction would cost $1.35 trillion.
For comparison that's 70 years of NASA's entire funding.
Edit: ah I skim read and that's for geostationary orbit. The prices for low earth orbit (where I guess they'd assemble this thing?) are less, $2,000-15,000/kg

That's where sea dragon comes in.
Another project dead before its time.
And project Orion would have been launched from earth.
Oh and it's only $4109 per kg, if you went with falcon 9
Nuclear ban research basically stopped all reaserch into nuclear pulse technology. There are lots of different configurations and not all weighing so much (longshot proposal was 400tons). Deadadlus was for long term human. Imagine what it could do for space probes at much lighter payloads.

Because once one lifeform established itself the chances of a competing lifeform establishing itself become vanishingly small.
EDIT: Seems the evidence points to life emerging on earth around 3.5-3.9 billion years ago. With the Earth being formed around 4.5 billion years ago and subjected to the impact that formed the moon and Late Heavy Bombardment up until around 3.8 billion ya. which quite possibly deposited a lot of the materials required to spur life into action.
It stands to reason that once life did establish itself, in the absence of any competition it quickly expanded to populate all habitable areas on the planet.

TL,DR: Life occurred pretty quickly once the conditions were suitable and once established no other competing form could gain a foothold.

I'm sure that there is life out there, if there are countless trillions of stars in a galaxy & there are countless trillions of galaxies of which many may be teeming with planets full of life of one form or another. Will they ever visit us? Can we ever visit them? I think not -particularly the latter.
Even a trip to a planet on our doorstep such as Mars will likely leave the astronauts permanently damaged because of gravitation problems, their first step will likely be a crawl.
Artificial mavity such as on captain Kirks starship Enterprise is a total misconception of scientific laws so astronauts are destined to float round like a helium balloon. Likewise spaceships spinning to give artificial mavity is another big fallacy as you would only end up being pinned against the wall with no chance of walking away from it.
Of course there are countless theories involving ships with a huge mass & decelerating from unbelievable speeds etc but will it ever happen

Space is so vast that even if there were thousands of intelligent species existing at the same time, it's likely impossible we will ever detect each other.
As for unintelligent life (excluding us of course), it's quite possible that exists elsewhere in our own solar system in some form, I can think of a few moons that have potential.

A rotating ship is theoretically possible. The force at the outer wall would depend on the size and the speed of rotation, so it is possible to make it 1g. You wouldn't necessarily end up being pinned against the wall with no chance of walking away from it.
The practical problems are big, though. You'd have a small inhabitable zone, only at the outer edge. The ship would pretty much have to be a hoop and it would have to be rather large because it would have to revolve slowly in order to not be a vomit-inducing merry-go-round. It would also have very limited manouverability, but that wouldn't necessarily be a problem. There's plenty of space in space
The rest, though, that's a different story. Spaceships in sci-fi can ignore it or make up technomagic devices as required, but reality is less malleable. Unless there's some way of taking extreme shortcuts, interstellar travel isn't going to happen unless it's unmanned with a very long journey time.

Aliens and stuff, watch this!

"Rendevouz With Rama" by Arthur C. Clarke. Good hard sci-fi. I'll keep spoilers to a minimum but it features a cylindrical vessel, very large. Other than the poles where it gets weird and trippy, that gives you pretty much maximum area coverage whilst using spin to generate 'mavity'. No hoop required.
what does that say about you being in bed w/ it then?
For some reason I hadn't thought of just making the hoop wider, i.e. a cylinder.
This has always made me wonder. Strange why black budget aircraft would be flown over populated areas, maybe to test the way people would react.
The speeds and manurers it pulled off are astonishing. Design is very interesting as it is blatantly not using 'conventional' thrust. The military report astounds me, as it pulled off 240 km/h to over 1,770 km/h while changing altitude from 2,700 m to 1,500 m, then up to 3,350 m before descending to almost ground level.

Never mind about build James Webb telescope to detect alien life.
NASA already did it with Hubble telescope since 1990 collected massive database with pictures of alien planets included Zeta Reticuli I wanted to see but governments don't want us to see. Same things with UFOs and aliens since roswell crash in 1947.
I wondered why governments kept whole things quiet and I am sure we can handle the truth no matter what the worst secrets they hide from us whether aliens lived on earth whole time before human or they created us and watched us grow up or something about cause mass panic nonsense etc.
National Security Agency was in contacted with aliens since 1947, they released unclassified NSA technical journal pdf on extraterrestrial messages but that was the only one and they don't want to release the rest of it.

Back in 2012 Russia PM Medvedev finally admitted the existence of aliens.

So I am ready to meet aliens and handle the truth. When will US government disclosure the existence of aliens and declassified all documents all agencies and NSA kept since 1947?

No known human technology is capable of photographing a planet 39 light-years away. Not even vaguely close to it. Not the Hubble telescope. Not anything else. You have been told things that aren't true.
