We live on a planet teeming with life, surrounded by strange and wondrous creatures—from insects to animals. So, would it be possible for aliens to exist today, or even live among us? 

You may be surprised to learn that NASA has studied the possibility of intelligent life in the universe. Their findings, some of which are quite extraordinary, may surprise you. Some of the mathematical equations that scientists use to determine the likelihood of life in the universe are so complex that they are indigestible to the human mind. There is no guarantee, but scientists are able to make an educated guess based on evidence from planets orbiting other stars and space debris around our solar system.

What do aliens look like?

With advances in science, however, we can now place much more of a name on some aliens. And while some aliens have human-like facial features, others have more strange features. But what makes an alien?

In recent years, astronomers and scientists have started to wonder whether aliens exist. What do we know about aliens? Do they look like us? Do they only exist in outer space? Are they dead or alive? The answers to these questions vary, but it’s safe to say that whenever we meet aliens—inside or outside of our solar system—we will indeed be meeting extraterrestrial life.

UFO Sightings: Fact Or Fiction?

UFO sightings are rampant throughout the US. Some even claim that over 90% of Americans claim they have seen a distant light in the sky. However, is it all just a hoax? Some people think so. There hasn’t been much hard evidence proving whether UFOs are real, but with a few research tools and creative thinking, it may be possible to identify which sightings are likely hoaxes or real.

UFO sightings are one of those topics that tickle people’s curiosity, but 9 out of 10 times, sightings could be nothing more than some bright stars. But not all sightings are purely natural. There have been reports of aliens visiting Earth in many forms, from spaceships to Earth-sized creatures.

UFO sightings are as common as rain or sunshine. People in all walks of life have reported seeing UFOs—and many have been caught on film. But are some of those sightings real, or just something seemingly unexplainable?

There exists scientific evidence of extraterrestrial life. Believers claim that extraterrestrials visited Earth in the past, leaving traces of evidence for their existence. The skeptics argue that UFO and alien sightings are the results of misidentification, hoaxes, or mass delusions. Although we cannot prove the existence of extraterrestrial life, it cannot be denied.

If you listen to conspiracy theorists, aliens are real. But if you talk to scientists, there are many explanations for what alien life might look like. To answer whether aliens are real, we need to define the term “alien.” Scientists define aliens as “beings from a different planet.” But why would beings from other planets visit our Earth?

It has long been a fascination of mankind to ask whether aliens exist. After all, who would pass up a chance to see a spacecraft land in your backyard or witness an extraterrestrial take off from a nearby sky? While we may never know the true answer to whether aliens exist, the questions regarding the existence of life on other planets and the possibility of first contact are valid to ask.

The evidence suggests that other intelligent species exist in the universe, though we cannot be certain. The Drake Equation, a mathematical formula that attempts to estimate the number of intelligent civilizations in our galaxy, suggests there might be as many as 10,000 others.
