Do Aliens actually exist ?

Intelligent life evolving on earth is miraculous - for many, many, many reasons.

And yet... are we earthlings alone - the sole life forms (or intelligent life forms) - in all the universe?
===
For me, this seems to be a nearly impossible proposition.

The elements necessary for life as we know it - are widespread in our own solar system. Might Mars, for example, once have harbored life?

And what about life deep in moon oceans here in our solar system - e.g., Europa? Or maybe under an alien atmosphere such as Titan?
===
And however miraculous life is on earth - are conditions for life on earth so astronomically improbable that the entire 13+ billion light years of observable space does not harbor at least one other planet blessed with such miraculous fortune?

And too? Is the universe, in fact infinite - that the universe continues much as we see it at infinitum, forever and ever, without bound - in spite of the fact that the speed of light and the age of the universe combine to limit our view to a subset of this infinity?
===
For me - aliens - and in fact intelligent aliens - almost certainly exist.
 
The universe is not infinite.
The conditions that need to prevail for life to develop as it has on earth are so astronomically improbable that I believe we are certainly alone in our galaxy, if not the universe.

Excellent. You are smarter than numerous PhD cosmologists on this very topic - I await your scientific publication proving that the universe is not infinite!

>> The conditions that need to prevail for life to develop as it has on earth are so astronomically improbable that I believe we are certainly alone in our galaxy, if not the universe.
The conditions for life to develop are in fact very rare - but not astronomically improbable - I rather think that life exists now or in recent past - within our own solar system - rather more likely than not.

Whereas the conditions for intelligent life, capable of travel through space - are rather much, much, much more demanding. In our galaxy - I think so - in the universe - possibly infinite - and even if not - I think that intelligent life capable of space faring in our universe - approaches near certitude.

Absolutely disagree, on both counts.

1. The universe may well be infinite. We have no proof either way at the moment.

But putting that aside,

2. it doesn't need to be infinite for life elsewhere to be a cast iron certainty. We have about 100 billion stars just in our own Milky Way galaxy. We know this - we don't need to speculate about infinities. We also know there are at least 200 billion galaxies, and possibly as many as 1 Trillion, in our observable universe. Maybe countless more beyond that.

So we have let's say 200,000,000,000,000,000,000,000 stars, and many of them - most even - are thought to have planets. Some may have 10, 20, 100 planets but let's say just 1 on average.

Then the universe is 13,800,000,000 years old. Or 662,000,000,000,000 seconds.

So you're asking us to believe that for 662,000,000,000,000 seconds on 200,000,000,000,000,000,000,000 planets there was NEVER a random chemical reaction which produced the building blocks of life. But it just happened by chance on our planet?

The chances of this being true are so astronomically - no pun intended - unlikely as to be rendered impossible. Life pretty much MUST exist of have existed elsewhere. Whether it ever became intelligent life is less likely, but given the ludicrous number of "attempts" and the ludicrously long amount of time, I think intelligent life is a cast iron certainty as well.

So where are all these intelligent aliens? Simple answer: They are out there, but they have no idea we are here. They cannot possibly know because we have sent them no signals. They are too far away to have heard a murmur from us. And space is so inconceivably vast and the planets so many in number, they have had no (un)earthly reason to visit us.

EDIT: I forgot to multiple that lot by about 133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. Which is the average number of atoms on each planet.
 
Am I right in thinking that universes are “small” parts of something much bigger (a multiverse) that looks like a load of bubbles?

Over time energy within the mass of this can create universes and while the energy of a universe can eventually run out (although that’s over trillions-x-trillions•• of years), the energy of the multiverse is never ending.

Is that right? I’m sure I’ve read or heard that from somewhere before.
Yes but it’s contentious (although based on facts known about our own universe).
 
Did anyone see Shaun ryder ufo series..they definitely exist. Todmorden is a hotspot

This is a nutty way of thinking!

Not only do we Humans develop our own concept of time that is unique to us, we seem to transpose that thinking on what WE measure as Human Beings.

Just to answer your second point in using my first as an example, why aren't we the only living organisms on this planet? Why are there flies, kangaroos, elephants, amoebas, etc? Each one of these organisms have their own way of communicating and have their 'societies' that we cannot begin to comprehend as 'intelligent' as we are as a species.

So, just using one of organisms; what are their concepts of time and existence?

I think it's beyond pure arrogance that any Human can think we are THE only existence when we can only see as far as "up the street" in relevancy terms.
 
If the universe is expanding, which seems to be the prevailing idea, then it can't be infinite. Unless by infinite you just mean bloody big.
 
Scientists estimate a total of 2.5 billion T-Rexes once roamed the earth.

2.5 billion.

Nowt to do with Aliens, but seriously. You wanna go exploring other planets? All that way, no coming back.

After hundreds of years in stasis, you find a planet with life.

Off you pop. Got your linguistics, maths, all your scientific stuff ready to go, ready to communicate with the aliens - whatever they are.

Open the door and ....it's T-Rexes everywhere, as far as the eye can see.

Nah mate I'm good make another brew stick Star Trek on.

Whatever.
You write gibberish.
Are you trying to claim that Einstein is wrong and that we invented time?
As for organisms, we are effectively the only living organism.
Everything that lives or has ever lived, plant or animal share the same DNA. From dinosaurs to humans, cauliflowers to algae the DNA is almost identical.
