Good post that mate. I too have seen things in the night sky that I can't explain rationally. I have spent a lot of time whilst night fishing just lying back looking at the night sky. Your eyes get in tune to the scene, and when something unusual happens it's obvious after a while.
Now I'm not saying there are flying saucers whizzing about as soon as we go to bed, but I've seen enough anomalies in the night sky to make me think maybe we aren't alone. Sounds irrational, and there are probably perfectly reasonable explanations for what I've seen.
I have a mate who swears he has seen a ufo land. He's a normal fella in every respect, not a pot head, not a big drinker. But he's adamant he saw one land one night when he was fishing. It's not even open for discussion as far as he's concerned, they exist.
