Maybe we make first contact

Most sci-fi scenarios I've seen involve us being contacted by higher forms of alien life.

But perhaps we are currently the most advanced intelligence (I know -- a bit Copernican of me, but still it's a thought exercise) -- are we trying hard enough to make first contact?

Carl Sagan designed a placard for the rocket (which one, I forget) -- this was at the information design exhibition at the design museum -- but it did not contain nearly enough information.

Here's what I suggest. Humans build a time capsule with all of human achievement encrypted onto it. It would need to be digital, so perhaps the basic encapsulation contains the instructions to build a media player, as well as the media player itself with components that should last 1 billion years (at least).

This time capsule is buried on the moon (in case we destroy ourselves) and also multiple versions are launched towards various galaxies likely to support life.
