Moon base, the year 2210
A tall, athletic person walks in the room. He sits to a round table just opposite of me. He is attractive with positive, smart but drilling eyes. He seems to wait for me to start the conversation.
Hello, nice to meet you. I am here because all our inbound communications are switched off. I was informed this is to do with some alien threads that we think would infect our systems.
We did not know you are contacting us. You are probably one of the long-lost human colonies.
He smiles. Yes, we tried to contact you. My apologies, we did not mean to be intrusive. After all, that time we had searched for this star, I think finally we found it. It matches our records perfectly. Though all constellations look somewhat different, the time difference can explain this. We sent as signal your way a long time ago, but it probably got lost in one of the interstellar dust clouds. This is very exciting to be here again and meet you. We call ourselves thinking beings as you do.
I am very surprised that we can’t find any records about your colony. Is it in Andromeda galaxy as you say? How is that possible?
We have some advanced propulsion systems. Though we can’t travel faster than light, we can bend the space.
I wonder what year your group left.
He smiles – You call it 1.500.125 BC
I just now noticed that he is much stranger and walked in a way I had never seen before.
Did they leave from Mars?
Yes, one spacecraft was sent out. Nobody was on the board, just a spacecraft for exploring another star system.
I can show you our latest spacecraft, but you must keep your space suit on as it has no life support system yet.
From this point, I knew what he is.
