There has to be life outside of our universe. There is an incredible number of planets and stars and galaxies beyond our own;a number far beyond human comprehension. Our evolution is imperfect and flawed, yet we have still become the most powerful and intelligent species within millions and millions of miles. Conditions like ours that can support life could very easily arise somewhere else in the universe. THere has been such a wide window of time, and so much space for it to happen, that it is inevitable that there is life somewhere else in the universe. If we can exist, why should we be the only ones?

There are many planets , with supstences of H2o *Water* on them . Where there is water there can be life. Since the earliest hominid species diverged from the ancestor we share with modern African apes, 5 to 8 million years ago, there have been at least a dozen different species of these humanlike creatures. Many of these hominid species are close relatives, but not human ancestors. But it only takes one to evolve creating a sucsessful species, just takes two animals with good offspring to create a more human like spcies.
Most scientist say that Earth started out as a *star* that was mostly mad out of valcanos, and that many meteors hit earth making its huge trenches within our ocean. But after all of the meteors hit earth , it started to rain , for Billions of years, Then formed an Ice age ... Which soon after melted making land and our oceans . And within our oceans life began...

But of course *humans were first evolved by creatures that lived in water . All there has to be within that water is bacteria, which could form into something over time. Then create a Ape like animal , *Which is a close ancestor to hominids*.


Well the point of planet earths history is , it could have happend some where else , within our Solar System or not. Maybe billions of light years away.


If you have any thing you would like to say just post on this fourm . Im going to keep this on my page. Hope it gets somewhere.

Enjoy!!

I doubt it will always go the same way. Even if it starts the same, there's a lot of environmental factors that force the species to adapt/evolve differently. A slightly different atmosphere (maybe 1% less oxygen, 1% more CO2 than earth had) early on in the formation of the planet could drastically alter every form of life on that planet.


yep thats reality.
but i was talking IF it was like that. if there would be humans in the other solar system.

Let's assume that one in a million planets have life every billion years. That means there is a 13.7 in a million chance that there has or was life elsewhere.


Let's take this estimate and run with it.
There is an estimated 200-400 billion stars in this galaxy alone. How of those there is an estimated 500 million planets in the habitable zone (we will ignore the possibility for life outside this goldilocks zone). There is an estimated 200 billion galaxies in the universe. Let's say for the sake of argument each of those galaxy has about the same number of possibly habitable planets. So that's 500,000,000x200,000,000,000= 100,000,000,000,000,000,000 possibly habitable planets in the universe. Now we divide that by 100,000,000,000,000,000,000/1,000,000= 1,000,000,000,000x13.7= 13,700,000,000 chances that there is or was life elsewhere, 6,850 per galaxy.

(If I got the math wrong sorry my mind decided to blip out half way through.)

I think that there could be a life on another planet, but I doubt that we'd ever find any. Even if we did find life on another planet, I don't think we'd ever be able to communicate with them or learn anything useful from them because they would probably be extremely different from us.

There would be a lot to be learned from finding life on another planet. It would give us information on the requirements for life and how life evolves.

The question of life being outside the solar system is kind of rhetorical. Each star you see out in the sky is a sun. Since there are more suns out there than there is grains of sand on this earth by times 10 then its only safe to assume that there is life. Actually, the possibility of there not being any life is incredibly small. MageGrayWolf explains it pretty well

I think there is life outside our solar system. Maybe other life wouldn't need air or water? Does anyone ever think of that. The universe is constantly expanding. Through a random process, or evolution maybe there is bound to be life out there somewhere. Most of our scociety is too closed minded to even be open to the possibility.

I think I remember running the Drake Equation using some figure from a creationist site that had just made up a big unlikely probability to make it sound like life forming on it's own was next to impossible. I still ended up with thousands of sentient lifeforms throughout the universe.

It doesn't have to be sentient either. It can just be bacteria and protocells. And then there are the planets that have good conditions for life but don't have it yet. The number of possibilities increases further!

I also forgot to include stars that no longer exist that could have had life.

The universe is just too big. The only answer I can see is that there has to be something out there somewhere.

From where we are now, we can see other galaxies. Who's to say there's not Intelligent life in those galaxies?

Or that them galaxies can see other galaxies.
We don't know how far out planets are.

Actually they can exist in places we can look. Yes just don't posses the ability to detect them yet.

It's not like we could see them lol , example *You look out the window on an airplan , they look like ants*. So it would be kind of impossible to see them , maybe in like a thousand years. Lol
