Carl Sagan called our world the tiny blue dot in a great speech. It's extremely difficult to imagine our tiny blue dot being the only place where life exists, especially when you see how it thrives in so many climates, under and above water, in the freezing water under an iceberg to the boiling water around the mouth of an undersea volcano.

The water bear is an excellent example of how life may travel from one world to another in the vacuum of space. If you haven't read about this little bastard, check it out. It's pretty astounding. Read facts 11 through 20 - [factslegend.org]

One of my favorite images on the subject.
With that much stuff out there how could there not be other wierd random stuff somewhere?

Belief or disbelief is not appropriate IMO, unless you just like to argue. I am certainly open to the idea of alien life, and there is indeed some evidence. There’s not enough of the kind of evidence that would be persuasive, so I’ll put the question on a back burner for the time being.

Here we go throwing around the 'B' word again. How do you define 'believe'? If it means to accept some proposition with inadequate or no evidence, then the answer is an emphatic no.

Here we go throwing around the 'A' word again. How do you define 'alien'? If you equate the word with intelligence wielding technology, then the answer is an emphatic I have no idea.

See, here's the problem. We are working from a sample of one. Based on what we know of how things work (physics/chemistry), we can say that probability would indicate that there is life of some sort somewhere else but here, but beyond that we can draw no conclusions. So, the answer to the question is generally as follows.

Given the presence of the same elements being available throughout the universe, it is reasonable to assume that there might be life somewhere besides here. The key here is 'assume'. We can't know until we find it. If we find a single microbe on a single body here in our solar system, we will have changed the nature of the problem radically. However, that would still not give us reason to think that intelligence capable of technology is out there as well. Intelligence is one thing. Being able to manipulate the environment is another.

Drakes Equation pretty much sums is up on the probability of life through the cosmos, and that probability is rather high.
Plus Dr. Neil DeGrasse Tyson in a book, and many talks show that what life on this planet is chemically made of, is the same 1 for 1 what the universe is made of. Being, Nitrogen, Oxygen, Carbon etc. the list goes on.

With that said, and other things, I can't see how life could not be elsewhere.

But as far as ever been visited by them. I'm not so sure about that.

In the sense that something exists somewhere in the universe, it's almost entirely certain.

In the sense that they're visiting Earth to strap people to their Probulator, almost certainly not.

The evidence is there it’s always been there but when you take in account that no one wants to be a cast out or risk defying their government because they’re already conditioned and loyal just as they were under religion.

Which surprises me when people who claim to be non believers of faith are so willing to perpetuate the ideology of the abrahamic faiths that there can possibly be no others because we are god’s Devine creation.

All while every civilization on the planet was pointing at the same constellation and saying that’s where we originated from. We have societies that never met and share little to identical alphabet or vocabulary but they all call those who have come from space the exact same name.

We’re still discovering petroglyphs and other anomaly’s that can only be seen from heights and distances that we weren’t able to achieved until the mid 20th century so once a fucking gain who was meant to see them?

But as I said I don’t ever expect anyone to share my level of beliefs in that we didn’t just show up out of a female chimpanzees birth canal nor did we crawl out of pile of dinosaur dung and the more sophisticated science gets the more it leans towards us not coming from the exact same location on this planet.

So I guess that only time and science will tell but until I’m holding to my beliefs as should y’all if that’s what you truly believe.

Yes. But I don't believe they have ever been here.

It is statistically impossible that we are alone in this galaxy, let alone the entire universe.

I do. Although there's no actual proof, I think there's life on other planets. In what form? Who knows?

Every day aliens are crossing the Mexican border and entering the USA.

Yes, but are likely to be some kind of microbe rather than flying around in saucers.

Beats the hell out of me I got other things to worry about ?

I dunno, but once while camping in N. Az. I saw ball lights that zigged and zagged in the sky at incredible speeds.... wasn't man made, and it wasn't ball lightning.....

Are we a lone?No. Are thet they visiting? No. Reason Simple, tooooooooooooooooooooo damn far. A bunch of other reasons too. But that reason is enough.

I can't wait for complicated extraterrestrial life forms to be scientifically proven. I wonder what religious nuts would then have to say about the role of their Gods in all that.

of course there is life "out there." it is probably microbial. the thing is, if you want to define life as something that resembles us, or even other animals, then it becomes less and less likely. life can come into being with the right chemical and environmental conditions. intelligent life... that takes more special circumstances, very specific courses of evolution that are unlikely to occur (evolution yes, those specific courses no) elsewhere. so if you're looking for someone who's looking for us, that's quite unlikely. and our existence isn't proof of anything relating to anyone else's existence. it might or might not be evidence. evidence and proof are not the same thing.

g

Yes. They are called bacteria.

As much as possible, my "beliefs" are based in evidence. I do have inclinations based upon extrapolation our existence and our observances.

The earth is in just the right orbit in the galaxy. It is in just the right orbit in the solar system. It is just the right size. It is just the right age. It has just the right amount of internal heating. It has just the right amount of atmosphere. It is special. As we are.

Can other such places exist? I think so. And I hope so.

Need to see it. Probabilities are strong, but until proven it doesn't matter about belief.

Always an interesting thought

They exist.

Yes

Given the unimaginable vastness of interstellar space I am inclined to think that we are not the only life forms in the universe. However, as to what form other life forms might take it remains largely a matter for the imagination.
