O.K, The big bang theory suggest that all matter and elements were distributed equally in all dirrection after the explotion, then why is life only here on Earth?
Should'nt life exist in allmost every galaxy in more than one solar system, under the right conditions.
Is it that we have'nt found any due to our lack of experience and time in space exploration, or that other posible forms of intelligent life havent found us?
With millions of years of life on this planet, just now is there a life form (humans) capable of space observation.
Other posible life formations on other solar systems may have had a greater time of evolution of "original Spieces", like reptilian evolution fron dynosaure eras, not wiped out by an asteriod.
Our existence as humans on this planet is just a fraction of a second compared to the total time of life that existed before us.
So are we really alone? Or did the big bang spread life thruout the universe?

1) Only hydrogen was created as a result of the big bang, and that took hundreds of thousands of years. We had to wait for massive stars to explode to get any other elements.
2) There is probably life out there somewhere - we've only really been to two other bodies to look for life (Moon and Mars) and didn't really expect to find it there anyway. We need more time.
3) Probably both - space is big. It would take a long time to get anywhere.
4) Life on Earth is Billions of years old, not millions. Evolution takes a long time.
5) Sure. But they had the same chances of being wiped out that we have. Only in the last few years have been been able to detect asteriod threats.
6) Again, the big bang didn't spread life. Just hydrogen. It all evolved from there (chemically first, then biologically). But it probably would have had to happen seperately on each planet, which makes life even more rare.

First, the big bang did not distribute matter equally, it distributed energy equally (in the first few seconds after the big bang, it was to hot for any matter to exist).
The energy coalesed into electons, and protons (along with the anti-electrons and anti-protons) and, eventually neutrons. These evenutally form hydrogen and helium. Eventually gravitational attraction caused these to coaless into stars and galaxies (the formation of heavier elements had to wait a few generations of stars).
(I left out a lot, but read Steven Hawking's "A brief History of Time" for more information)
Second: Most scientist will agree that the possibility (indeed, the probability) of life on other plants is likely.
Intelligent life? That can not be known until communication between us and them is made.
What shape do they have? Again, unknown.
Anyway, I don't see any paradox in any of this. . .

Those early particles "evolved" into the elements we know today. Elements created in stars. It can take several lifetimes of stars to construct the heavier elements.
There could be (or have been) life on other planets within our solar system. Or, it could be on another solar system within our galaxy. We're just beginning to look and it takes a lot of time for light to travel that far. What we're looking at today occurred hundreds to thousands to millions of years ago.
If you enjoy this type of thing then you should take an astronomy class.

No. Univer the Randomisty theory the Cosmic Casino threw a lucky 7 with us.
Right place, right times, right chemicals, right gases, right temperature, right distance from the sun, right sun, etc.
According to the religious there we were created here on purpose.
We don't truly know we are alone, but the universe is not necessarily teaming with life.
With Las Vegas Odds on the Randomist side there could be dozens of worlds at various points of development.

Considering we know of 10 planets in our solar system and the only place besides Earth man has reached is the moon HOW might I ask , WOULD YOU FIND LIFE ON ANOTHER GALAXY ?!
Seriously , why would you ask such a pointless question? You wasted 5 points on basically an amped up version of "Are we alone?" . I've answered many stupid questions but THIS my good sir , is the WORST.
/end rant.

there are just special conditions which exist for us here on earth, the distance from the sun is ideal for life, and our mass is great enough to keep our electromagnetic feild, protecting us from harmfull radiation. i do believe that there might be other life out there, but we haven't been able to reach far enough to discover it. we could be the only life in our whole galaxy, so it could be many, many years before we develop technology great enough to discover other life. there is also the theory that the big bang didn't really happen, seeing as calculations dont work in the miliseconds after it supposedly happened. the string theory says it might have really been two universes colliding, and ours might not be the only universe. it is very complicated. this is all very controversial and depends on what you believe.

Im not so sure that the big bang theory says all elements were equal in all directions....
anyway, our galaxy is really big, so everthing's really far away, so life might be out there...just not detectable yet....and the other galaxies are so far away, they're not even worth worrying about trying to look for life.

Our solar system is only one of billions in the Milkyway Galaxy. And there are an infinite number of galaxies in the universe. Who ever said that we were the only life in the universe? To say that would be rediculous.

THERE ARE AN ESTIMATED 10,000 EARTH-LIKE PLANETS IN THE MILKY WAY GALAXY ALONE! To believe that we are alone in the universe and that none of these 10,000 planets (that could be considered twin planets of earth) have spawned any life would be very naive. The odds are so great that I would consider this to be a certainty.

might the main superb answer no longer count upon the size of the pin? If neither time nor area exists, then is length no longer arbitrary. without time and area there might nicely be no definitive characterization of a pin's rather life, no longer to point its length. additionally, has absolutely everyone ever rather considered a 'huge bang' dance?
