What do you think about extraterrestrial life or what is also called alien life?
Extraterrestrial life, also called alien life (or, if it is a sentient or relatively complex individual, an "extraterrestrial" or "alien"), is life that occurs outside of Earth and that probably did not originate from Earth.

Extraterrestrial life
Extraterrestrial life, also called alien life (or, if it is a sentient or relatively complex individual, an "extraterrestrial" or "alien"), is life that occurs outside of Earth and that probably did not originate from Earth. These hypothetical life forms may range from simple prokaryotes to beings with civilizations far more advanced than humanity. The Drake equation speculates about the existence of intelligent life elsewhere in the universe. The science of extraterrestrial life in all its forms is known as exobiology. Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial life.
Fermi paradox
The Fermi paradox or Fermi's paradox, named after physicist Enrico Fermi, is the apparent contradiction between the lack of evidence and high probability estimates for the existence of extraterrestrial civilizations. The basic points of the argument, made by physicists Enrico Fermi (1901–1954) and Michael H. Hart (born 1932), are: According to this line of reasoning, the Earth should have already been visited by extraterrestrial aliens. In an informal conversation, Fermi noted no convincing evidence of this, leading him to ask, "Where is everybody?" There have been many attempts to explain the Fermi paradox, primarily either suggesting that intelligent extraterrestrial life is extremely rare or proposing reasons that such civilizations have not contacted or visited Earth.
Potential cultural impact of extraterrestrial contact
The cultural impact of extraterrestrial contact is the corpus of changes to terrestrial science, technology, religion, politics, and ecosystems resulting from contact with an extraterrestrial civilization. It is closely related to the search for extraterrestrial intelligence (SETI), which attempts to locate intelligent life as opposed to analyzing the implications of contact with that life. The potential changes from extraterrestrial contact could vary greatly in magnitude and type, based on the extraterrestrial civilization's level of technological advancement, degree of benevolence or malevolence, and level of mutual comprehension between itself and humanity.
Douglas Vakoch
Douglas Vakoch (born June 16, 1961) is an American search for extraterrestrial intelligence (SETI) researcher, psychologist, and president of METI (Messaging Extraterrestrial Intelligence), a nonprofit research and educational organization devoted to transmitting intentional signals to extraterrestrial civilizations. On February 13, 2015 he engaged in a debate at the annual convention of the American Association for the Advancement of Science (AAAS) on whether humankind should send signals to other worlds in hope of reply. Vakoch advocates ongoing transmission projects, arguing that this does not increase risks of an alien invasion as suggested by British cosmologist Stephen Hawking.
Search for extraterrestrial intelligence
The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets. Scientific investigation began shortly after the advent of radio in the early 1900s, and focused international efforts have been going on since the 1980s. In 2015 Stephen Hawking and Russian billionaire Yuri Milner announced a well-funded effort called the Breakthrough Initiatives. There have been many earlier searches for extraterrestrial intelligence within the Solar System.
List of Alien characters
"Alien", a science-fiction action horror franchise, tells the story of humanity's ongoing encounters with Aliens: a hostile, endoparasitoid, extraterrestrial species. Set between the 21st and 24th centuries over several generations, the film series centers around a character ensemble's struggle for survival against the Aliens and against the greedy, unscrupulous megacorporation Weyland-Yutani. The main series consists of four films, "Alien" (1979), "Aliens" (1986), "Alien 3" (1992) and "Alien Resurrection" (1997), about Ellen Ripley's fight against the Aliens. Ripley is the sole survivor of an Alien rampage on the space freighter "Nostromo", which leads her to a series of conflicts with the species and Weyland-Yutani.
Ethics of terraforming
The ethics of terraforming has constituted a philosophical debate within biology, ecology, and environmental ethics as to whether terraforming other worlds is an ethical endeavor. On the pro-terraforming side of the argument, there are those like Robert Zubrin and Richard L. S. Taylor who believe that it is humanity's moral obligation to make other worlds suitable for Terran life, as a continuation of the history of life transforming the environments around it on Earth. They also point out that Earth will eventually be destroyed as nature takes its course, so that humanity faces a very long-term choice between terraforming other worlds or allowing all Earth life to become extinct.

I am conflicted regarding the subject.  I want to believe but am skeptical.

I am not sure I believe their are aliens or a life form that does not originate from Earth.

List of Ben 10 aliens
This is a list of aliens on Cartoon Network's "Ben 10 franchise". Voiced by:  Heatblast is a Pyronite from the star Pyros. He appears as a magma-based lifeform whose body is composed of a bright inner magma body covered by a reddish-brown charcoal-like crust. Heatblast is essentially "living magma", thus everything he touches either melts or catches fire. In the original series, he is the tenth alien in the Omnitrix. Heatblast is Ben's first transformation, accidentally activated and started a wildfire in the pilot episode of the original series, "And Then There Were 10" when Ben was trying to remove the Omnitrix immediately after it first attached to him.

Civilizations in Babylon 5
"This article discusses fictional civilizations on the science-fiction television show Babylon 5." As the Babylon station was conceived as a political and cultural meeting place, one of the show's many themes is the cultural and social interaction between civilizations. There are five dominant civilizations represented on Babylon 5: humans, the Narn, the Centauri, the Minbari, and the Vorlons; and several dozen less powerful ones. A number of the less powerful races make up the League of Non-Aligned Worlds, which assembled as a result of the Dilgar War, which occurred 30 years before the start of the series.

Each of the villains has been sorted into the TV series that he or she debuted in. Voiced by: Vilgax is a warlord who is Ben's first and most recurring nemesis through the series. Being of the Chimera Sui Generis (named after the mythological Chimera) race, who are able to turn into giant squid-like creatures when exposed to water, Vilgax was exiled from his home world for being ruthless, cruel, and power hungry. Soon after, Vilgax meets Maltruant as depicted in the Omniverse series finale which had him indirectly learn of the Omnitrix's existence when attacked by George Washington and a mysterious figure later revealed to be Ben.
List of Doctor Who universe creatures and aliens (Q–Z)
This is a list of fictional creatures and aliens from the universe of the long-running BBC science fiction television series "Doctor Who", including "Torchwood", "The Sarah Jane Adventures", "K-9" and K-9 and Company. It covers alien races and other fictional creatures, but not specific characters. Individual characters are listed in separate articles. Note that some information on the page is taken from spin-off media. The Quill were a humanoid species from the planet Rhodia who had a long history of war with the other species on Rhodia, the Rhodians. All the Rhodians and the Quill were killed by the Shadow Kin, except the Prince of Rhodia and Andra'ath, the Quill freedom fighter who was indentured to him via an Arn in her brain.
List of Alien morphs in the Alien franchise
The Alien franchise features several morphs of the Alien life form. This includes different castes, hybrids, mutants, and genetically engineered forms, which are listed below. Aliens are depicted as eusocial life-forms with a defined caste system which is ruled by a queen. Their life cycle comprises several distinct stages: they begin their lives as an egg, which hatches a parasitic larval form known as a facehugger, which then attaches itself to a living host by latching onto its face. The facehugger then "impregnates" the host with an embryo known as a chestburster, which, after a gestation period of several hours, erupts violently from the host's chest resulting in the death of the host.

I don't believe there has been any reliable proof of life outside of Earth, right?

yes, thats what I think.  the science of extraterrestrial life in all it's forms is known as exobiology.  I didn't know they had a name for it.

Astrobiology
Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth. Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does. The term exobiology is similar but more specific—it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things. Astrobiology makes use of physics, chemistry, astronomy, biology, molecular biology, ecology, planetary science, geography, and geology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth.

Carl Sagan
Carl Edward Sagan (; November 9, 1934 – December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space: the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them.

Brookings Report
Proposed Studies on the Implications of Peaceful Space Activities for Human Affairs, often referred to as "the Brookings Report", was a 1960 report commissioned by NASA and created by the Brookings Institution in collaboration with NASA's Committee on Long-Range Studies. It was submitted to the House Committee on Science and Astronautics of the United States House of Representatives in the 87th United States Congress on April 18, 1961. It was entered into the "Congressional Record" and can be found in any library possessing the "Congressional Record" for that year. The report has become noted for one short section entitled "The implications of a discovery of extraterrestrial life", which examines the potential implications of such a discovery on public attitudes and values.

I have never heard of that name.  How can there be a name if there has never been any discovered?
