It's a huge, huge leap from "Unexplainable things are happening" to "These are alien spacecraft." Agreed. You can't stop at "Unexplainable things are happening" without being told "They can't be, because interstellar travel is impossible." Also agreed. We need to be able to divorce analysis of the actual phenomena - whatever they actually are - from one specific speculative hypothesis.
