Do aliens walk amongst us?

[davidworth]

I was thinking that if an alien civilization came to Earth thousands of years ago and took human form, they would have enough time to adapt and adjust to human behavior and society. If that is the case, then how would you be able to tell who is or who's not an alien.

I kind of believe this theory. With all the craziness going on in the world, sometimes it seems deliberate. Almost like someone or something is trying to keep mankind divided. Maybe it is some kind alien forces working behind the scenes to keep us weak and divided.

I believe more along the side of believing that there is a native human-like species that has been here before mankind and has evolved along with us. So, when you think about it this way you start to think that maybe the lizard people theory is possible.
