We Don't Know (What We Don't Know)

The more that we know
The more we don't know
The deeper we look
The deeper it goes
The higher we fly
The higher the sky

The more that we search
The more that we're lost
The more that we save
The more that it costs
The more that we see
The more mystery

We don't know what we don't know
We don't know what we don't know
We don't know
We don't know what we don't know
We don't know what we don't know
We don't know

Bumping into mystery
In everything we think and see
We don't know
We don't know
We don't know
