i think it would be wise for you to register in a class of english grammar before you attempt to ask questions of such complexity/your phrasing makes you sound like a drunk

The question is hard to fillow, but let me see if I can give you the answer you are looking for.
First we must look at the possibility that there is life in the universe other than ourselves.
In the 1960s, Frank Drake proposed a formula to calculate the odds:
N= [r* x fp x ne x fl x fi x fc] L where:
N= number of possible civilizations to communicate with
R* = is the rate at which stars capable of sustaining like are formed
fp = the fraction of these stars which have planets
ne = the number of planets similar to Earth in the planetary system
fl = the fraction of the Earth-like planets that hold life
fi = the fraction of life that becomes an intelligent civilization
fc = the fraction intelligent civilizations that attempt to communicate
L= the number of years the civilization remains able to communicate.
Then you consider the additional factors of a civilization actually venturing out into space, if they will discover a method for travelling great distances (will they be long lived or will they develope hibernation techniques or will they develope multiple generation ships or will they learn how to get around the light barrier) and what are the odds that of all the many places in the universe to visit, what are the odds that they will pick our planet.
All these factors compounded indicate that while it is probable that over millions of years we will certinaly encounter extra terrestiral life, it is less probable that we will do so in the near future.
But the probability, however small, is not zero.

Do you mean: Is there any extraterrestrial life on the Earth? It is entirely possible that all life on the Earth was seeded from space through comets or other space junk. It only takes 50 million years or so for matter to be spread throughout the Galaxy so if life is created somewhere, it can spread anywhere.
If you mean: :"Are there little green men?", the answer is almost certainly no.

According to the string theory proposed by the scientists of the CERN and the FERMILAB, an extra terrestrial life is existing somewhere in this universe. Well, then they may someday come and conqure us.
According to the origin of species theory proposed by Charles Darwin, after a million years from now, humans will be eradicated and a new form of life more inteligent than the humans will evolve.

jUST WILL NOT, DO THE MATH THE CLOSEST STAR IS SEVEN LIGHT YEARS AWAY, light travels at 176,000 miles per second x 60x60x24 the distance you can travel in one day, think about it. Getting a spaceship into space with enough fuel is not possible, even if you could get it up to light speed it would take to much time and to much fuel, and then nearly the same amount of time and fuel to slow it down when it gets there. What about all the food for such a trip?

what?? Do you mean if there are any extra terrestial life forms on earth?? More than likely somewhere.

I do not think that this will be possible.However there are chances that we may come in contact with extraterrestrials in near future.
