The whole assumption/connection of UFOs to extraterrestrials has to be eliminated in order to understand what these objects truly are. For some reason for decades the majority of people simply cannot think in a scientific way about UFOs, it's like they are blocked. Yes there are exceptions of people but they usually get ridiculed. If we start from the premise that UFOs exist, stop thinking aliens and see what else is there then maybe we will get to the truth. Other options we can look into: 1) Someone or some people have the technology to build these. We simply don't know who they are and what they represent 2) It's a natural phenomenon that can be explained but needs proper investigation 3) They are drones from our planet but maybe built at a different time remnants or an old civilisation. Do we understand the entire history of earth and it's past civilisations? Maybe yes but also maybe we are missing something 4) Theory of multiverses and other dimensions could be something to think about 5) Or they are simply projections to our brains sophisticated enough to make us think these things actually exist It could be none of the above and just governments messing around with us in order to see how we react but this has to be one of the most complex and long term projects any government has got into. Point is more people need to look at this scientifically rather than dismiss all the evidence straight away.
