Out of these, what have you invested time in? For example, when I was in middle school and delivering papers early in the evening, I swore I saw a UFO. It looked like a small saucer shaped disc in the far distance towards a bright morning sun. It wasn't easy to look at as the sun was near and bright, but I stopped folding papers and watched as it was very fast and it zigged and zagged out of my sight. It probably lasted less than a second, but I thought it was longer than that. If another boy was with me, then I would have said something to him. Another time, I saw something similar traveling in a car in the back seat in my teens. It looked and acted like a saucer shaped object I saw in my middle school years. This time, I saw it for a few seconds. Maybe around 3. I thought it was just the reflection of the sun as this at an angle. I didn't say anything as it disappeared quickly. Later, when I was doing night patrols and driving a patrol car at late night parallel to a main road and telephone and electricity wires, I saw lights, but it was following in my direction. It turned out to be reflection of the lights in the distance against the night sky and the wires. Very tricky.
So, out of all that you list, I would say it was evolution that I invested the most time in learning. Until I had something to compare it to, I believed in evolution. Nothing spiritual at all about it. Global warming came second. When I compared it what other scientists were saying, then I stopped being concerned about it and realized it a trick like the UFO. What bothered me most was why Al Gore didn't conserve and why the business people who fly in private jets kept flying in private jets. Such hypocrisy. The only time I enjoyed it was when Gore threw his Live Earth concert in 2007. I'll still watch youtube replays. I think they're were other announcements for another bash, but it didn't materialize. What happened? Terrorism get in the way?
