X7

"Human? No, I am not. I am X7 serial code 238745. I am nothing more than a humble android." X7 replied. An android…. I walked up to X7 and looked him over, and even poked his face. Everything about him felt real. As I did this, the girls all watched me with great diligence, as if they were waiting for it to attack me at any moment. I could have told them that it was fine, but this was a good chance to let them learn to always be on guard. 

"How long have you been in operation?" I asked. Since it was able to tell that we were people, then it may have some valuable information.

"According to my creation date, fifteen million years have passed," X7 replied. But I guess my question was too broad. 

"Let me ask you this. When was the last time you saw a human besides us?" If I narrow it down this much, I should be able to get a better date on when this place was once a thriving place.

"Three days ago," X7 replied, causing me to raise an eyebrow.
