    why

That part I can answer at least.

We look, to the best of our ability, because of what a shame it would be if someone, something somewhere, was trying to reach us, and we weren't even trying to listen.

If you try and fail at a noble goal, there is some honor and dignity to be had. Nothing but shame if we don't even try. Plus the search for ET has lead to lots of advances in radio telescopes.
