Your opinion on alien lifeforms?

Post here your thoughts on alien lifeforms, and its existance or disexistance.
Do you believe that alien lifeforms have visited earth?
Do they even exist?


I think that there are other lifeforms than ours, but its very unlikely that they have visited Earth.
First, the possible existance of Aliens. Just in our solar system, there is atleast one planet with life, possibly others. It is likely that Mars atleast had some kind of bacteria life. Satellites have found out, that under the icy surface of Europa ( on of Jupiters' moons ) is a salty sea, much like ours.
Also Ganymedes and Titan may be able to keep up some kind of life.
So, if only in our solar system there is atleast four objects to keep up life, what's the possibility that there is life outside our own solar system?
Only in our galaxy, there are BILLIONS of solar systems. Each solar system contains atleast one star. Almost all stars are able to keep up life.
If 50 % of stars have stone planets like ours, theres is a big possibility that there is life in our galaxy.
Now put together that, and the fact, that there are billions of galaxies in the Space.


Now, the possibility of Aliens visiting Earth.
Our nearest star is the Sun. Second nearest is the Proxima Centauri is 4.22 AU away, for example the distance from Earth to Sun is 0.016 AU. ( 1 AU = the time light travels in a year, appromaxitely 9.461 billion kilometres )
So, if light travles 10 years only second nearest star, and nothing can move faster than light, it would take a LONG time to get to another solar system thats able to hold life. And if we predict that Aliens haven't invented a super fuel, they're going to run out of fuel before getting here. Ok, they could use solar power, but it's VERY slow when there is no suns nearby.


Well, chances are that there are other life forms than ours. But they probably haven't visited Earth.



Your opinions?

 

I have seen them i believe in them 100% proof 0 but thats just my opinion!! We are in a galaxy there are how many galaxy's??? yeah and people are saying out of who knows how many galaxy's theres not at least one more planet with life i call bs there is 100% for sure something someone else out there!!!

 

Yes, that's what I'm trying to point out on my writing. It is more than 95% sure, that there is life in outer space.

 

Do you understand how light travel works? Have you read anything on quantum physics or the theory of relativity? Just because human technology isn't capable of it does not mean it isn't at least plausible.

And 'super fuel'? . Again, do you know how energy works? Do you know what fusion is? Your two threads are both entirely speculative and have no real grounds for any scientific acceptance.

The possibility of extraterrestrials visiting Earth is low for one reason and one reason alone, and that's because the size of the universe. The probability is low, but that doesn't mean it's impossible. There's also really no reason to come here. We're still in the infant stage of energy, space exploration, and genetic evolution. IF there is other seemingly higher intelligent life in the universe, then they'd have no interest in us.

 

Theory of relativity states that NOTHING can move faster than light.
And have I studied fusion? I am FOURTEEN years old. Enough said?

Maybe my theories aren't perfect, but name a theory that is.

 

There are billions of Galaxies most of them contain 100+ billion stars. (100-300 Billion in our own galaxy which is average to small in size)
Each star can contain multiple planets, most of these planets are gas giants that don't contain any life forms.
But even then there are probably 100+ billion planets that can contain life...so not believing in external life is a bit silly if you ask me.

 

No, as I will explain it is almost impossible they could have.

Almost certainly. Our planet isn't that special, there are billions like it that could hypothetically support some kind of life.

So which is the 'atleast one planet with life'? These are just plausible predictions.

I quote from Superstition by Robert Park

 

I'm also FOURTEEN YEARS OLD, that doesn't give me the excuse to be a complete idiot.

 

Who said that gas giants don't contain life forms?
It is 100% possible that odd, floating animals could live there, on the outer gas part.

On our planet, theres life almost 12 kilometres under sea surface, so why not on gas giants?

 

How am I complete idiot?
