There is truth in what Justine says.

Science does not know enough yet to draw any final conclusions about the 'why' or 'how' of existence.

And science is constantly forced to reorient itself.

Until recently scientists were convinced that most of our DNA was 'junk'. Now we see that most of that non-coding DNA actually serves a purpose.

So Justine is correct - science has not yet finished listening (but it feels sure enough of itself to make some grand pronouncements).
