Plenty of amazing natural phenomena exist on earth beyond common knowledge, and can help in the effort to validate unidentified sightings. The information here is important to consider when making a credible claim, as it will help with the identification proccess. Should a claim be tainted by the presumption of non-earthly origins, it compromises the hypothesis and undermines serious investigation.
Remember when you are looking up beyond the stars, that our own planet is full of natural wonder and mystery as well.
