I believe in Aliens but it wasn't always so. I worked nights and one morning after work I saw a spaceship and a grey creature coming out of it. 2 other workers also saw what I saw... the space ship was in a lane and the Alien was look at the ground it seemed and then went back into it's space ship. Then a darkness came over the spaceship and was no longer visible. Half an hour later the darkness cleared and the ship and alien was gone. There was no evidence of it ever being there. The other 2 workers said not to say anything about it to any one and I agreed. I never believed in aliens until that morning. The occurrence happened in Thunder Bay Ontario in 1973 Fort William side. 8 AM don't remember which day it was.
