It's nice to know that we agree on some things. However, I think that it is necessary that some of the aliens come from the future or some other point in time because in order to have made alterations to the time-stream, something or someone would've had to travel to another point in time and change some part of that past or future. It's not enough for someone to just know enough about the time-stream if they don't travel in it.
