Probably. I also had a weird vision like that over these things, and it looked like they were in the desert out there as well.

[ It's not too strange of an idea, considering it had seemed like people had been living there.. Even if it didn't seem to end up very well for them, huh. ]

Except the people I heard were discussing stuff people like us might have discussed. People who came from other worlds. I guess it means there were probably groups like us in this place, and probably lived there, even if we haven't heard a single thing from them since we showed up.
