If it doesn’t exist, you can’t see it.
Therefore if you can’t see it, it doesn’t exist.
An easy mistake to make, but a mistake nonetheless.
Absence of evidence is not evidence of absence.
There are plenty of things we aren’t aware of. That doesn’t make them any less real.
We don’t know what we don’t know.
In fact there are far more things we don’t know than those we do. But once we realise this, we can adapt. We can prepare so we aren’t caught off guard.
It can also make the impossible seem possible. We don’t see a solution now. That doesn’t mean there isn’t one.
There might be an absence of evidence.
But maybe we’re just looking the wrong way.
