TNG: The Chase
You're wondering who we are, why we have done this, how it has come that I stand before you, the image of a being from so long ago. Life evolved on my planet before all others in this part of the galaxy. We left our world, explored the stars, and found none like ourselves. Our civilisation thrived for ages, but what is the life of one race, compared to the vast stretches of cosmic time? We knew that one day we would be gone, that nothing of us would survive. So, we left you. Our scientists seeded the primordial oceans of many worlds, where life was in its infancy. The seed codes directed your evolution toward a physical form resembling ours. This body you see before you, which is, of course, shaped as yours is shaped, for you are the end result.The seed codes also contained this message, which we scattered in fragments on many different worlds. It was our hope that you would have to come together in fellowship and companionship to hear this message.And if you can see and hear me, our hope has been fulfilled. You are a monument, not to our greatness, but to our existence. That was our wish, that you too would know life, and would keep alive our memory.There is something of us in each of you, and so, something of you in each other. Remember us.
