Doesn't the avoidance of your home prove intelligence?

Do Aliens actually exist ?

If they do exist we have not seen them due to the distance and time it would take for anything to reach us.
The universe is far too big for anyone to say either way as we do not have the technology/science to find concrete evidence.
True enough. Even if the universe is teaming with life, the reality is that the vast majority of the alien civilizations have no clue we exist, since we've only been broadcasting radio signals for circa 100 years. So for any civilization more than 100 light years away, they have no clue that earth is anything other than a rather boring blue planet. And only civilizations 50 year light years away or less, would have had time to spot us, and to send a signal back which we could pick up about now.
i.e. bugger all chance, since our own galaxy is a mere 50,000 light years across, i.e. a 50 light year sphere in a galaxy 1,000 times bigger, is tiny. Let alone the fact that the next *nearest* galaxy is 2.5 million light years away.
Our expanding sphere of man-emitted radio waves is a tiny speck, and to anyone outside that bubble, we don't exist and they have no conceivable reason to visit us.
The entire point that we’re so young as a civilisation, compared to the universe, is evidence against aliens though.True enough.

It’s estimated to take 10 million years to colonise a galaxy and harness all the star’s power, within that galaxy, to have renewable energy.
Even with our galaxy being a few billion years old, if aliens are out there we should be able to at least see one civilisation across the night sky, but we’re met with dead silence.
So where is everyone?

Civilisation advancement is far too slow. If you look at the big picture we are all caught in a social loop. As a race we have become lazy with an all encompassing small life mentality.
We don’t strive to conquer space. Life should exist based on the enormity of space but we lack the intelligence and fortitude to find the answers.
Unless they come to us we will never know.

According to Jaques Vallée, it's inter dimensional :) (isn't he the guy who has a character based on him in Close Encounter of the third kind).The entire point that we’re so young as a civilisation, compared to the universe, is evidence against aliens though.

Still, aliens aside....love to know what all this flying tech is.

It’s absolutely nailed on that there millions of planets with life out there.
Have they ever been here? I wouldn’t bet my life on it but there’s an absolute ton of important and high ranking people who say they have.
Just say we had been contacted or had been visited, does anyone think that we’re ready to hear it? We can barely handle people from other countries on our own planet without wanting them kicked out or starting wars.
If aliens made contact tomorrow then I just don’t think there’s a chance they would make it public and that’s why I think there’s always a question mark.
I mean when you hear stuff like this it does make you wonder:
The astrophysicist Eric Davis, who consulted with the Pentagon’s original UFO program and now works for the defense contractor Aerospace Corporation, told the Times that after he examined certain materials, he came to the conclusion that “we couldn’t make [them] ourselves.” In fact, Davis briefed a Department of Defense (DOD) agency as recently as March about retrieving materials from “off-world vehicles not made on this earth.”

The furthest point in the universe that we can visibly see from Earth is 45 billion light years away.The entire point that we’re so young as a civilisation, compared to the universe, is evidence against aliens though.

It stretches a lot further than that!
There will be countless ‘ideal’ planets in ideal solar systems in ideal galaxies across that expanse that have the right conditions to have intelligent civilisations.
We will just never find them and they will never find us.
He knows a lot more than I and I am totally unqualified in this assessment but I’m going to go with he’s talking shite :-)According to Jaques Vallée, it's inter dimensional :) (isn't he the guy who has a character based on him in Close Encounter of the third kind).

Other galaxies have no evidence of star light being used for energy either. Our galaxy is completely silent, which I think is evidence, whether it proves it or not, that we are alone.
Obviously there’s evidence for both sides of the argument, I’m just merely stating why I think we are.

God knows what your 2nd paragraph is all about. But the other 3 are reasonable comments.The entire point that we’re so young as a civilisation, compared to the universe, is evidence against aliens though.

My personal feeling is that the universe is probably teaming with life, but - two important points, (i) most of it is plankton and (ii) space is so inconceivably enormous that spotting intelligent life is unthinkably difficult.
Imagine intelligent life is quite "rare". Let's speculate for sake of argument that in the average galaxy like the milky way, with its 100 billion stars and 1 trillion planets, only 1 planet has intelligent life on it. That would mean life is incredibly rare, right?
But there are perhaps 200 billion galaxies, so on that basis there would be 200 billion civilizations out there right now. The problem is there is no conceivable way we could know - no radio broadcast would ever be strong enough to be detectable from millions of light years away. Even if these civilizations existed millions of years ago, and their electro-magnetic emissions had time to reach us, we'd never be able to hear them. And they would never have thought to visit us (assuming they had the technology to do so, which is extremely unlikely anyway) because they would have no clue we are here. Why launch such an expensive intergalactic mission to visit our small insignificant speck, which to them would appear lifeless anyway?
