If you want it to, what are the odds of a UFO coming back to me?

last night me and my friend saw what was prolly a UFO, it was visible for about only 5 minutes, it had only one light, an orange light in the front, then when it changed its direction the light dissapeared and there were none bellow it or in the rear of the craft.....so I stayed up last night outside wanting it to come back, what are the chances that it will come back?
