I hate being alone but I’d to follow my last orders from my masters. Just one order, ever so simple, though difficult to comply with. I had to find the best planet for human life in our infinite universe as soon as possible.
A very puzzling request if you know there are millions of stars out there where rarely you're able to find some planet where life might exist. According to my latest estimate, there are more than one thousand eight hundred exoplanets just in our galaxy and as you know the Milky Way is just one galaxy among millions of them.
But now my search had been stopped by a message from earth. That was very unusual. Such a heavy file with lots of encrypted information and a text message. It was one month ago and I hadn't seen what the file contained yet but the message said: "What a disaster! It's our end. You must...". The message didn't continue. That was all. Then I tried to contact with the earth but I couldn't.
After a short time coming back to earth I knew why they didn't answer: the earth had gone. Where the earth had been, there was just a deep darkness. No place. No time. Nothing. It was so confusing. I wondered what had happened and what to do next.
Consequently, I wandered in my space ship for three days. Then I had a memory of my training days on earth. I remembered what was said by my master every morning before the training: "All our lives in your undying life". At that moment I understood what I had to do. My task had changed slightly. I rebooted the ship and started a new mission leaving everything known behind.
Now I was really alone but the most important was being carried into space.
