If you look at most natural disasters and disasters such as the Japanese power plant, there always seems to be videos of of UFO's. "Post Hoc, ergo propter hoc"
Post hoc ergo propter hoc, Latin for "after this, therefore because of this," is a logical fallacy (of the questionable cause variety) that states, "Since that event followed this one, that event must have been caused by this one."
Post hoc is a particularly tempting error because temporal sequence appears to be integral to causality. The fallacy lies in coming to a conclusion based solely on the order of events, rather than taking into account other factors that might rule out the connection.
