Another galaxy just like ours with a sun and planets that revolve around it?

I don't think that fact means that it is obvious that there is other life in our universe, let alone intelligent life.  (BTW, I think you meant to say solar system instead of galaxy.  A galaxy is made up of many solar systems. )  I'd like to hope that with so many large galaxies out there that there is the possibility of one having a solar system that is capable of creating life.

Lets look at the maths. If every star in this galaxy was a grain of sand ( approx. 100 billion ) you would have enough sand to fill an Olympic size swimming pool. how many habitable planets around each star ? Between 0 and 5 maybe. \n  There are approx 100 billion galaxies. Again if each star was a grain of sand  there would be more sand than on every beach on earth. The chances are there is life elsewhere and in all probability the seeds of life on earth came from somewhere else  as explained by the panspermia hypothesis.\n   And the alien abductions? ,,,we're just studying  8)

the Milky Way is a galaxy

Our galaxy is the Milky Way.\n\nThe story I heard spoke of a Greek god who was carrying cans of milk to Mt. Olympus when he tripped and spilled the milk across the sky.  The milk became the band of stars we see splashed across the night sky.

Our solar system is not the only solar system in the universe.  There are hundreds and thousands and millions of other planets in the universe, and many are just like ours, but we don't know about them because we have never been able to get anything further than pluto to get a good specific picture of stuff.  In a general picture, though, we do know there are other galaxies in the universe

Do you mean SPIRAL galaxies?\n\nCompare the Milky Way (our "spiral" galaxy) with others in the universe. There's a classification for spirals, so it shouldn't be that hard to write a paper on it (without be a physicist)

Water is a necessity for life and that is based on temperature more so than which planet you are from the sun, it could be the tenth planet from the sun as long as the temperature is similar to ours here. \nBut with so many galaxies and suns in the universe I'm sure somewhere there is another world much like our own.\n\nHeres something you might like it shows everything that we are able to see in the universe and zooms down to our solar system.\n\nhttp://www.atlasoftheuniverse.com/universe.html

Definitely. What are the odds that, among all the gazillions of planets and stars and galaxies, not ONE other life-form has developed? Hell, I don't even care if we can find sentiency, if there's just LIFE somewhere I'll be happy.

No.\n\nGalaxies are groups of stars and planetary systems.\n\nA single sun (even ours) is not powerful enough to have a galaxy rotate around it (gravitationally speaking).\n\nDoesn't work that way.  We move around inside the galaxy, not the galaxy around us.

Galaxies are a collection of billions of star systems (like our solar system) all rotating about one central mass, called the galactic center.   They are the largest "structures" in the universe, and there are as many galaxies out there as there are stars you can see in the night time sky.

Planets like Mars, Jupiter.  The stars that are so far away that it takes light hundreds of years to reach Earth from there.\nGalaxies that contain billions of stars. We are in a Galaxy called the Milky Way.  The Ocean.

Rephrase your question sweety, the Milky Way & the Galaxy are the same, but there are other galaxies than ours. then... different than what? are you smoking something?

YES. There are many stars in our galaxy with solar system formed.

I go with the Big Bang theory and that our planet just happened to be in the right place at the right time. If our planet grew life then there is the possibility that other planets in other galaxies grew life as well. We just happened to get the right amount of heat and light from the sun.

A recent scientific study estimates that there are AT LEAST 70-sextillion stars in the universe, one of which is of course are own sun. The odds AGAINST none of those other stars having planets occupied by sentient life are astronomical (pun intended). Undoubtedly of all the life forms that exist in the universe some are technologically at the same level as we are, while others are at least several thousand years ahead of us. Still others might be where we were 3-million years ago---just down from the trees. Certainly, any alien life with any intelligence at all must wonder if there are other life forms somewhere other than their own world.

There is a possibility of other living matter existing other than the humans.There are billions of stars and there may be many more earth's around them.When the conditions of existance of life prevails ,like for earth -water,atmosphere,essential gases and many more exist.Ofcouse there may be different conditions in other galaxies but there is a possibility that life exists.Them being friendly or visious depends upon the way we try to communicate with them.If the way we communicate is wrong they may prove to be more visious than friendly.
