What If We’re Actually From Mars?

What If?

Here’s a weird thought: our bodies might be hinting that we aren’t originally from Earth.

Everyone knows Earth spins once every 24 hours. That’s what we base our entire lives on—day, night, sleep, work, everything. But when scientists take people and stick them in places where they can’t see the sun and don’t have clocks, something interesting happens: our internal rhythm doesn’t stay at 24 hours. It stretches out to almost 25 hours on its own.

Why would our bodies want extra time?

Now here’s where it gets interesting. A day on Mars is 24 hours and 40 minutes. That’s way closer to the biological clock humans fall into naturally than Earth’s perfect 24.

So either that’s just a huge coincidence—or maybe not.

Another thing most people don’t know: Earth didn’t always have 24-hour days. In the distant past, Earth spun faster. The days were even shorter, and over millions of years the planet slowly slowed down because of the Moon’s pull. So if life started here, why would we be built around a longer day than Earth used to even have?

Put it all together and you get a fun possibility: maybe our distant ancestors weren’t from Earth at all. Maybe life—at least the kind that eventually became us—came from Mars when it still had water and a better atmosphere. Maybe we brought our internal clock with us.

It’s obviously speculation, but it does make you think. Our bodies might remember something our history books don’t.
