At last, I've found another ship! My spacecraft's power cells are almost dead, and I don't have enough fuel to go any further. You're my only hope. I've been traveling for 500 years looking for another life form with compatible DNA to fertilize my eggs. I come from a planet you call Kepler-438b, and I am the last of my kind. Are you the one I've been seeking, the savior of my species and eternal hero of my heart? With your help, I can repopulate my planet. All you have to do is give me your sperm.
