The jury’s out. On all of it.

What do we really know? We’re stuck to a spinning orb of dirt in an infinite universe of other orbs, with no proof yet that any of those contain other life forms or civilisations.

There’s a lot we don’t know, although we’re very good at inventing ‘facts’. In fact, we get so involved in what we’re doing here on our minuscule plot, we find it hard to see outside of our own little world and its preoccupations.
