Is there life on other planets?

Thanks alot. I also want to know if there is existence of people on other planets rather than aliens? People like us humans?

You'd need to talk to an exo-biologist to get that percentage.

But yeah, it's logical to assume that on planets where water is that life would evolve as a bipedal structure be it reptilian (some therapods were as smart as a dog before they were wiped out) or mammalian.

Of course on places like Titan you'd expect life to be very different, there are likely several forms of life.

Wow, I've never heard of Titan. Where did you hear about it?

It's a moon orbiting Saturn. It's the only moon in the solar system with an atmosphere and evidence of liquid on the surface. It's also the only place other than earth where all the elements needed for RNA and DNA have been found.

Not that you could breathe there. It's about -150C and the liquid is Methane based.

Once the sun becomes a red giant in a few billion years it will probably get very toasty given that Methane is a greenhouse gas.

Well it sounds better than our moon rotating around the Earth! Ours has no oxygen!

Is it said proven that the sun will be red giant in a few billion years?

Indeed, it's a very interesting world whether there is life or not. Completely unique in the solar system versus Venus and Mars which were both quite earth like with water at one stage.

Yes, around 5 billion years. But in around 2 billion the moon will decouple from earths orbit meaning that the earth won't be able to maintain life anyway (the moon acts as an anchor, without it the earth could become tidally locked with the sun (always facing one side).

Evidence please

So, through Nasa as i heard have found that there is life on other planets. So are there any evidences if it does exist? So are there human being like us on other planets?

NASA directly contacted you to inform you that there is life on other planets?

Yep!

I don't believe they are among us, but maybe watching us.

I believe in aliens, the Illuminati and things surrounding this. I also believe conspiracies about 9/11 which involve the Illuminati.

I won't discuss this with someone who doesn't believe, but anyone who does it is great to have a talk about it! always learning new things.

If you don't believe, just ask yourself one question. Do you truly believe this is all their is, to us, to life, to the universe?
And as you most likely won't believe in 'god' How did we get here? As the big bang theory hasn't been proven either.

And when i say aliens, I don't think they are little green men. I think they are way way beyond anything we could imagine.

It's been getting leaked into the public eye for years, its only a matter of time. But as of right now we are not ready.

If G.W.Bush was to go on TV now and say, hey guys well in fact my names bob and I'm an alien. There would be chaos and the world would be destroyed.

There are two schools of thought (so nobody really knows) but this article is a good assessment of both. In the worst case scenario earth would become tidally locked.

That 2 billion was also the worst case scenario, some models indicate the sun will gobble us up before the moon becomes an issue.

If they found life you would probably know (:

i do believe there is life out there

partly because if we as a species are the only dominantly intelligent life out there, then you can consider life a failed experiment seeing what a mess we are making of our planet
