yes...but they are far beyond our reach and we cannot determine what they will look like we think.there are some stories surrounding this theory...u can read the book "chariots of gods?'' its amazing and thought provoking..
Many scientists believe that if extraterrestrial life exists, its emergence occurred independently, in different places in the universe. An alternative hypothesis is panspermia, which suggests that life might emerge in one location and then spread between habitable planets. These two hypotheses are not mutually exclusive. The study and theorization of extraterrestrial life is known as astrobiology, exobiology or xenobiology. Speculative forms of extraterrestrial life range from sapient beings to life at the scale of bacteria.

All life on Earth is based on the building block element carbon with water as the solvent in which biochemical reactions take place. This carbon and water combination may have formed other creatures on other planets with roughly the same make up. Due to the fact that Earth (and subsequently, all life on Earth) is made up of "star dust" or rather mass formed from stars which have gone supernova, it is apparent that the millions of other stars which can even be seen from Earth have been formed by the same sorts of particles. The combination of carbon and water in the chemical form (CH2O)n, is the chemical form of the sugars, which as well as providing the energy on which animal life depends (largely through the oxidation of glucose, a six carbon sugar), also provides structural elements for life (such as the sugar ribose, a five carbon sugar, in the molecules DNA and RNA). Plants derive energy through the conversion of light energy into chemical energy via photosynthesis. Life requires carbon in both reduced (methane derivatives) and partially-oxidized (carbon oxides) states. It also requires nitrogen as a reduced ammonia derivative in all proteins, sulfur as a derivative of hydrogen sulfide in some necessary proteins, and phosphorus oxidized to phosphates in genetic material and in energy transfer. Adequate water as a solvent supplies adequate oxygen as constituents of biochemical substances.

Hindu beliefs of endlessly repeated cycles of life have led to descriptions of multiple worlds in existence and their mutual contacts ( Sanskrit word Sampark (समपर्क) means 'contact' as in Mahasamparka (मह‌समपर्क) = the great contact). According to Hindu scriptures there are innumerable universes created by the Supreme Personality of Godhead to facilitate the fulfillment of the separated desires of innumerable living entities. However, the purpose of such creations is to bring back the deluded souls to correct understanding about the purpose of life. Apart from the innumerable universes which are material, there is also the existence of unlimited spiritual world, where the purified living entities live with perfect conception about life and ultimate reality. The life of these purified beings is centered around loving devotional services to Supreme Personality of Godhead. The spiritually aspiring saints and devotees as well as thoughtful men of material world have been getting guidance and help from these purified living entities of spiritual world from time immemorial. However, the relevance of such descriptions have to be evaluated in the context of a correct understanding of geography and science at those times.
Scientists are directly searching for evidence of unicellular life within the solar system, carrying out studies on the surface of Mars and examining meteors that have fallen to Earth. A mission is also proposed to Europa, one of Jupiter's moons with a possible liquid water layer under its surface, which might contain life.

In 1961 astronomer and astrophysicist Dr. Frank Drake devised the Drake equation, which mathematically simplifies the rate of formation of suitable stars, the fraction of those stars which contain planets, the number of Earth-like worlds per planetary system, the fraction of planets where intelligent life develops, and the fraction of possible communicative planets, and the "lifetime" of possible communicative civilizations which scientifically stated there are an estimated 10,000[25] planets containing intelligent life with the possible capability of communicating with Earth in the Milky Way galaxy.

The presence of space aliens on Earth or in the atmosphere is only slightly more probable than the existence of the Easter Bunny.

So the answer with 99.999999999999999% probability of being correct is NO.

Yes, aliens are true. You got to research more on them. I got lots of evidence and one such interesting news that one who has met with the alien and has also shown his video with the alien. If you still don't believe, there's news about him as well.

On average aliens probably make as many mistakes as real people. But like SOME real people they always try to learn and get better.

According to every alien I've spoken to.

There is a high probability that intelligent life exists elsewhere in the universe. But there is absolutely no credible evidence that it has ever visited Earth.

aliens are not true.it is our faith on aliens make it true to somebody.even no one confidently prove that they see it.in our solar system or milky way no planet is prove to be fair to generate life.even more they chould not contact us yet.something can be true that any other planet chould have small bacteria type micro life but "they are not aliens".

Yeah may be.... But so far no one has discovered any true aliens....And who says they may actually be out there....
