One thing I wonder about the mystery of flying objects is that flying is still a new-ish phenomena to us so there is such a weird amount of mystique about it and gives hoaxsters an advantage. Partly because it does make sense that if aliens from another planet were to come here, it would be by flying but there is never a ground vehicle of any sort that they bring with them also? We barely venture out much to other planets but with what little we have, we have land rover vehicles to cross lots of terrain. Aliens wouldn't do that to a degree or a boat of some sort considering how much water is on this planet. Just a funny thing I'm wondering about at the moment.
