If the earth was the only planet in the universe to have life on it, it would be 1 in a 100 sextillion chance or 1 in 100,000,000,000,000,000,000,000. To give a comparison, that is the same odds of winning the lottery 6.6 quadrillion times. (average odds of winning the lottery is 1 in 15,000,000) Where did I get this number from? Scientist estimate there is somewhere around between 125 to 500 billion galaxies in the universe and in every galaxy there is between 10 billion to several trillion stars in each. I simply took 250 billion galaxies times 500 billion stars since each star has a chance of having a planet that has life on it.

Can there be life beyond earth?
The question asks can there be life beyond Earth, and statistically the answer is almost certainly yes. The Earth falls in what is colloquially known as the Goldilocks zone - not too big, not too small, not too close to the sun, not too far away, the sun is not too hot, not too cold, etc. So finding another planet in the Goldilocks zone should be quite rare - let's say one in every million stars..Not to good odds for life elsewhere you might think. But consider this. There are over 1 Billion stars in the Milky Way Galaxy alone, and over 1 Billion galaxies in the universe. If the odds of having a life sustaining planet is 1 in 1 Million stars, then statistically we expect there are over 1,000,000,000,000 (that's 1 Trillion) life sustaining planets in the Goldilocks zone right now!.Our universe is so stunningly vast and plentiful - and yet on average so empty - it defies all human comprehension. But can there be life beyond Earth? Absolutely.
Is There Any Living Human Beings On A Planet?
No because Earth is the only planet that has life and other planets are too near and too far from the light and atmosphere has to be oxogenNone on this planet have gone out and colonized other planets. If there are any humans for any reason out amongst the stars not of our world, we have not yet met them.
What other Planets in Our Galaxy have enough Oxygen to Sustain Human Life?
If a star system has planets, the availability of oxygen on a given planet is a complicated process. If the planet is of the correct size and in the ecosphere of the star, the production of oxygen will occur through the existence of plant life that will convert carbon dioxide into oxygen. In a primordial planet like an earth, oxygen is not going to be an element that is naturally occurring. The compound carbon dioxide is. It takes plant life to produce an atmoshpere that will sustain animal life.The odds of this happening in a given star system are low, but possible.
Is life found on the other planets?
This is a question that is not yet answered. Scientists estimate that the universe has millions billions of planets. Life as we know it, require certain parameters to develop of which these are just a fraction:1. Being located on a planet with water and carbon (for carbon based life forms)2. Being located the right distance from the sun also commonly referred to as the Goldilocks zone (too far and it will be too cold; too close and it will be too hot)3. Life must have had a chance to develop; e.g. generally the conditions must not change dramatically, too fast. For example, earth's tilt towards the sun has been stable and no doubt a factor in the development of life on earth. Plants with changing tilts could prevent life from developing even if other factors were present.4. the existence of larger planets in the outer layers of our solar system has protected earth against possible bombardments of asteroids5. the size, composition, atmosphere, and position of the earth must be just right.It is very clear that the conditions for life is extremely difficult to establish as so many factors have to be just right over a very long period of time. However, when you consider the number of possible planets in the universe, it is quite conceivable that the odds for life is possible.
How many planets contain life?
So far as we are aware, intelligent or otherwise, one. The earth. However, it is likely that some form of life exists on potentially billions of planets in the universe, and odds are that some of them have developed intelligent life. Billions of planets are out there. A tiny fraction may be similar enough to Earth to have generated life. A tiny, tiny, tiny, tiny number of those Earth-like planets that have generated life (one-celled creatures) MIGHT have life that has evolved up into walking, swimming or flying animals. A tiny, tiny, tiny, tiny number of THOSE planets may have life that has evolved into something that is is able to use tools, say, a sign of intelligence. (Higher intelligence comes from the 'accident' of the first pre-human to have opposable thumbs . . . that is, thumbs that can touch their fingerprints to the fineger prints of the other fingers.) The number of planets that would have intelligent life similar to ours is infinitely small. So . . . consider that 'life' may have evolved on other planets that are NOT based on carbon and oxygen. Perhaps there are creatures, for instance, that breath Methane, and are made of silicon. (Wild example, but . . . . ) At the moment, we still do not know if there is life on any of the other planets in our own Solar system! Mars could have some micro-life forms, and also some of the moons of Jupiter. Jupiter and the other gas giant planets in our Solar system could have created life in their hugely varied atmospheres, but if so, they would likely be nearly unrecognisable to Earth humans.
What are the chances that earth is the only planet with life on it?
If the earth was the only planet in the universe to have life on it, it would be 1 in a 100 sextillion chance or 1 in 100,000,000,000,000,000,000,000.

What are the odds of life occurring in the universe?
The probability is 1, since it has already happened. There has been life on earth for millions of years - long before humans.
Are their ailien on mars or any other planets?
Even though we can be pretty sure about no intelligent life-form on Mars, we do not know in regards to other planets in other solar systems in the universe. Scientists today believe that the odds of Earth to be the only planet in the entire universe with life is astronomical. We can not know for sure until we get confirmation one way or another. There are a few practical problems of getting this information though.
What are the odds of another earth type planet in your galaxy?
1.5 Multiplied by 10 to the 17th power.

When did God die?
Answer: God didn't die. His son Jesus died on the cross for our sins and rose again.God is not dead, He was there at the beginning and He will be there at the end. There is science and math. The universe is billions of years old, and evolution is a fact. There is also a God who runs it all, because the odds against something like the Earth being a perfect planet for life, (a "Goldilocks" planet where everything was just right), are unbelievable. There is no way it just happened by random. God is real, and if it weren't for God, it would not be as good for human beings as it is on the planet Earth.
Why is that the earth is the only planet that can support life?
earth has oxygen and water to supply humans, plants, and animals to live here.Of the planets that we are aware of, Earth is the only one that has life forms. However, there are Billions of galaxys, each with Billions of planets, so the odds are extremely likely that there are other planets that have life forms.Earth is the only planet that can support life (As far as we know) because we have a breathable atmosphere of Oxygen, which is essential for life to exist. We are also the perfect distance away from the sun, which means that the water on our planet does not vaporise away or freeze forever. I guess you could say we got lucky.We are not sure that there is or is not life on othere planets... But some of things that we think a planet needs to support life are water, heat, cold, and an a atmosphere ... As far as we know... Mind you that life can live in the most inhospitable of places'...
Why is it that only Earth has the right mix of substances to support life?
This is mainly due to luck. Earth happened to be the right distance away from its star and had the right history to develop life. The odds that all the conditions required for life come together is very small, but there are billions of planets in the universe, so it is likely that more than a few have struck the right combination. It is also possible that life formed in a way different from how we know it, so the conditions for life may not necessarily be the conditions required for our life. It is very possible that we are not alone in the universe.
Is There Any Living Human Beings On A Planet?
No because Earth is the only planet that has life and other planets are too near and too far from the light and atmosphere has to be oxogenNone on this planet have gone out and colonized other planets. If there are any humans for any reason out amongst the stars not of our world, we have not yet met them.
What do you call the only planet inhabited by man?
If man developed on this planet first and only, then the Earth or Tellus is the only planet inhabited by man. It might be disputed if our planet is the first one or the only one. Science does not know for certain but the odds with to days knowledge are against theories of man coming to earth from other planets.
Is there any proof of life?
On Earth, yes. You are it!Elsewhere, no. The odds of life elsewhere seem high, but odds are not proof. Someone has to be the first form of life in the universe, and it may well be us.For a while it was thought that a Mars meteorite had fossilized microorganisms in it. Most scientists now believe they were just bits of mineral. So much for proof!(Please note that violating copyright by cutting and pasting articles is plagiarism.

Does UFOs really happen to appear?
Well most are probaly halluginations some drunk people wondering around and getting high on weed 0_o but the odds are in the entire universe with all of the stars a planet is bound to be orbitting one and if life has evolved to such extent that it is able to reach far off galaxies, who knows?
