It sounds a bit "tin-foil hat" until you actually look at the math. For decades, saying i believe in aliens was basically social suicide in scientific circles, or at least a quick way to get labeled as the office eccentric. But things have changed. Dramatically. We aren’t just looking at blurry photos of weather balloons anymore. We’re looking at data from the James Webb Space Telescope (JWST) and declassified sensor footage from Navy fighter jets.
The universe is big. Like, "can't even wrap your brain around it" big. There are roughly 200 billion stars in our galaxy alone. Most of those have planets. If you do the math—the Drake Equation, which was cooked up by Frank Drake back in 1961—it becomes statistically improbable that we are sitting here on the only rock with a Wi-Fi connection.
The Drake Equation is basically a cosmic lottery
Most people who say i believe in aliens point to the sheer scale of the universe. Frank Drake’s formula isn't a "fact" in the sense that it gives us a hard number, but it’s a framework for high-level guessing. It looks at the rate of star formation, the fraction of those stars with planets, and how many of those might actually support life.
When Drake first wrote it, we didn't know if other stars even had planets. We were guessing. Now? We know. Thanks to the Kepler mission, we’ve found thousands of exoplanets. Some are hellish landscapes of molten glass. Others are "Super-Earths" sitting right in the "Goldilocks Zone" where water doesn't just boil off or freeze into a solid brick.
What the UAP Reports actually told us
Let’s get real about the "UFO" thing for a second. The Pentagon doesn't even call them UFOs anymore; they’re UAPs (Unidentified Anomalous Phenomena). This shift in branding wasn't just for fun. It was a move toward legitimacy.
In 2021 and 2023, the Office of the Director of National Intelligence released reports that basically admitted there are things in our airspace that we cannot identify. These objects move in ways that defy our current understanding of physics. No visible wings. No exhaust. Instant acceleration that would liquefy a human pilot. Does this prove they are "little green men"? No. But it does prove that something is happening that our best tech can't explain.

Avi Loeb, a Harvard professor, has been a huge voice here. He’s the guy who suggested 'Oumuamua—that weird, cigar-shaped object that swung through our solar system in 2017—might have been an artificial light sail. He got a lot of heat for it. But his point is solid: why do we assume every weird thing in space must be a rock?
Life doesn't need to look like us
We are carbon-based. We breathe oxygen. We need water. Because of this, we tend to look for "Earth 2.0." But that’s a pretty narrow way to view the universe. Astrobiologists are now looking at the moons of Jupiter and Saturn, like Enceladus and Europa. These places are icy shells, but underneath? Massive, salty oceans kept warm by tidal heating.
If we find even a single microbe swimming in the dark oceans of Europa, the phrase i believe in aliens goes from a fringe belief to a biological certainty. It would mean that life isn't a fluke. It’s a feature of the universe. It happens wherever the conditions are even remotely "good enough."
Why haven't they called us yet?
This is the Fermi Paradox. If the universe is teeming with life, where is everybody?
Maybe they’re using communication tech we haven't invented yet. Maybe they’re looking at us like we look at an anthill on the side of a highway—interesting for a second, but not worth talking to. Or maybe, as some theorists suggest, there’s a "Great Filter." This is the idea that civilizations tend to blow themselves up or get wiped out by climate change before they can figure out interstellar travel.

It’s a grim thought.
But honestly, the lack of a "Hello" doesn't mean the house is empty. We’ve only been broadcasting radio signals for about a century. In cosmic time, that’s less than a blink. Our "radio bubble" has only reached a tiny fraction of the stars in our immediate neighborhood.
Redefining the Search
The search for SETI (Search for Extraterrestrial Intelligence) is shifting away from just listening for radio pings. Now, we’re looking for "technosignatures." This includes things like:
- Atmospheric Pollutants: Using telescopes to find CFCs or other industrial chemicals in the atmosphere of a distant planet.
- Dyson Spheres: Hypothetical structures built around stars to harvest energy.
- Mega-structures: Odd light fluctuations in stars (like "Tabby's Star") that don't fit the pattern of a passing planet.
We are no longer just waiting for a phone call. We are actively peeking through the neighbors' windows with high-powered sensors.
What you can actually do with this information
If you're someone who thinks "i believe in aliens" is a logical stance, you don't have to just wait for the news to break. There are ways to engage with the data yourself.

The Galileo Project, headed by Avi Loeb, is looking for high-quality data on UAPs using non-classified sensors. You can follow their publications. You can also participate in citizen science projects like "Planet Hunters" on Zooniverse, where regular people help find exoplanets in NASA's data that the algorithms might have missed.
Keep an eye on the upcoming launches. The Europa Clipper mission is going to be a game-changer for finding life in our own backyard.
The most important thing is to stay skeptical of the "woo-woo" while remaining open to the data. There is a massive difference between a grainy video of a bird and the mathematical probability of life among the billions of galaxies. We are living in the first era of human history where we actually have the tools to answer the question once and for all.
The odds are no longer on the side of the skeptics. The more we learn about the extreme environments where life can thrive on Earth—from volcanic vents to frozen lakes in Antarctica—the more likely it seems that the universe is a very crowded place. We just haven't been introduced yet.
