What if you found out that you had a long-lost relative? And what if that long-lost relative was from a different planet in our galaxy? And what if this faraway planet was home to billions of humans, just like Earth?

But these “humans” don’t look anything like us. Because they’re from the future. Could aliens be future versions of humans? How far ahead of us would they be? How much would they have evolved?

Would we be able to understand each other? What would meeting future humans mean for humanity on Earth?

In 1947, a mysterious object crashed in the desert near Roswell, New Mexico. You all know this story. But could it really be aliens? The mysterious object was officially declared to be a US Army Air Force balloon.

But then, decades later, U.S. Navy Commander George W. Hoover, who had top secret clearance, revealed that the mysterious crash involved time-traveling humans. Somehow, these future humans had developed the technology to overcome the technological limitations that prevent us present-day humans from making the same type of trips.

Some theories suggest that these future humans travel back in time in order to understand their biological past. Maybe these same time travelers helped our ancestors to make huge leaps in scientific and technological knowledge in a relatively short amount of time. ”

But if any of these theories are true, should we be prepared for another alien-human visit sometime in the near future? And what might we expect from this close encounter of the third kind?

If aliens, I mean future humans, were to come and visit us again, they would probably look similar to how they appear in movies. Like us, they’d still walk on two feet. But their heads and their eyes would be much larger.

This fits with predictions of how present-day humans will continue to evolve. We can expect our heads to be bigger and our upper skull become more rounded to accommodate a larger brain. And as our civilization advances enough for interplanetary travel, our eyes would get bigger so we can see better in dimmer environments that are further away from the Sun.

Future humans might also find a way to slow the ageing process. So it would be possible to make several trips to places thousands of light-years away within one lifetime. If we want to travel somewhere that’s 60,000 light-years away, and if our technology could do it, then it would be a 60-year flight for anyone onboard. But when they got back to Earth, 60,000 years would have passed.

We’d like to think that humans of the future would solve this problem, so they could visit Earth and come home to tell their family and friends about their trip. But if future humans find a way to live for thousands of years, would that lead to massive overpopulation on whichever planet they inhabit?

Chances are, if they make it possible to live that long, they will probably succeed in optimizing their existence before that. Their civilization would undoubtedly be a lot more efficient than ours.

The reason being is they could be centuries, if not millenia, ahead of us in evolutionary terms. Future humans would be a lot smarter, and they’d have better technology to maximize their space, and live in densely populated worlds without producing the same high levels of pollution that we do on Earth.

In fact, you could bet that future humans wouldn’t just have better technology, they’d be technology. Just like some humans today have implants to perceive sound or to detect atmospheric pressure, the humans of the future would likely have dozens of technological implants to make their lives easier. Think about everything your cell phone does for you. Now, imagine that you could command it with your thoughts, and that it would only be a small chip in your brain.

A chip, or an implant like that, might also explain why those who claim to have encountered aliens, have said that the aliens spoke to them in their native language. Could future humans simply have automatic language translators implanted in their brains? Or would humans of the future evolve past different languages? Instead, they might use just one universal language like Esperanto.

But then, if we could communicate with aliens, or future humans, what would you ask about first? Would you want to learn how to time travel? Is time travel even possible? Or is time itself just an illusion?
