Some say it’s obvious we’re not alone, others scorn the very idea and still others yet will hauntingly report their own experiences of alien probings following their casual night-time stroll through the fields of small town America. But with everything from increasingly bizarre reportings from increasingly credible sources, to basic mathematical probability suggesting the likelihood of alien life, these days, scepticism is harder won. Whatever your opinions, you may well find that the following examples have some impact on them.

The concept of extraterrestrial life, and particularly extraterrestrial intelligence, has had a major cultural impact, chiefly in works of science fiction. Over the years, science fiction has introduced a number of theoretical ideas, each having a wide range of possibilities. Many have piqued public interest in the possibilities of extraterrestrial life. One particular concern is the wisdom of attempting communication with extraterrestrial intelligence. Some encourage aggressive methods to make contact with intelligent extraterrestrial life. Others argue to do so may give away the location of Earth, making an invasion possible in the future.

The unsolved sightings are the other major evidences that make aliens more real.
There are more registered sightings of UFOs than there is the word count here to deal with them and the majority of the time, there’s a thorough debunking accompanying them. But throughout history there have been a number that have been harder to explain away, from the to 1853 sighting by a number of students and professors at the Tennessee College campus, to the oft quoted Stephenville Lights case from 2008, with over 200 witnesses spotting the UFO including three policemen who remained anonymous. Consider these compelling cases unsolved.
