a question for the believer in chemtrails

 

why is it that sometimes you can see your own exhalation and sometimes you can't?

could it have anything to do with the temperature and humidity of your breath and the temperature and humitdy of the surrounding air?

why would you assume that the air many thousands of feet above you is the same temperature and humidity as the air you are standing in?

does the temperature and humidity have anything to do with whether or not a contrail is visible? or how long it's visible?

could wind speed and direction control how much a visible contrail spreads or doesn't spread
