The ETH is perfectly healthy

Might there be a contrasting option to the extraterrestrial speculation? Well you could conjecture that they originate from a parallel universe or another measurement or some such. That is still extraterrestrial in my book. That leaves the likelihood of physical and subsequently human time travelers from our future. I mean it's conceivable. Who's to say something else? But, in the event that human visitors from our future can time travel back to our time and before then you'd expect a horrendous part of UFO reports to revolve around exceptionally critical authentic occasions like the JFK death or the sinking of RMS Titanic or D-Day or the primary utilization of the nuclear bomb, or Custer's last stand, or maybe parcels would have showed up over Yankee Stadium when Roger Maris hit his 61st grand slam. About the nearest you get is the "Star" of Bethlehem occasion at the introduction of Christ - and even that is just related in one part of the New Testament. So the time travel speculation is a disappointment.

One exceptionally strong contention for the UFO ETH is that over almost seven decades now the extraterrestrial speculation hasn't possessed the capacity to be exposed. Nobody can concoct a feasible option speculation. The ETH is perfectly healthy. Why? There must be something going on that is suggestive in the compelling that the ETH is the best (and most likely just) speculation to manage those no-nonsense UFO sightings. There must be a clarification for them and every single other situation have been dispensed with. Perusers may review the well known Sherlock Holmes cite: "When you have dispensed with the inconceivable, the straggling leftovers, regardless of how far-fetched, must be reality." If the no-nonsense UFO buildup isn't outsider, what's an option theory?
