There are many things
We don't know are real.
From scientific theories
To the forever concealed.
What could be false,
And what could be true?
If you were to ask me,
Humanity never knew.

First up in my list are pretty unicorns,
With majestic manes and glittery horns.
Nobody's ever found one, maybe nobody will
But that won't stop some from trying, still.

Next on the list is maybe the ghosts,
Transparent and spirited, the one of which most
People believe in, but I am not sure
If they can be real. We'll keep searching for more.

Third one's the charm, please meet Bigfoot!
Is he really as real as the fireplace soot?
But if you're a hunter, please beware,
Killing him's illegal in Washington... how rare!

Mermaids are next, at the fourth spot.
When it comes to my reasons, I know quite a lot.
5% of the oceans is all we've explored,
So they might be out there, trapped forevermore.

Last but not least, and this statement's quite bold:
We can never prove the existence of the soul.
What does it look like? Where does it go?
Those are some things I'd like to know.

There are many things
We don't know are real.
From scientific theories
To the forever concealed.
What could be false,
And what could be true?
If you were to ask me,
Humanity never knew.
