This is IMHO really the best hostile to UFO ETH

Protest: It's far-fetched in the great that we (people) would simply happen by chance be the fortunate era, following 4.5 billion years have passed Earth by in astronomical confinement, for us to now encounter nearby enormous organization. If you somehow happened to toss a dart haphazardly at 4.5 billion inflatables, what chances that it would hit an inflatable that coincided with mankind's presence, notwithstanding being liberal and giving us (humankind) a presence of say two million inflatable years, far less hitting the inflatable named 1947 (the acknowledged begin of the cutting edge UFO period)?

ANSWER: This is IMHO really the best hostile to UFO ETH contention going yet when taken to its legitimate decision gives the very answer which makes the UFO ETH about unavoidable. For sure, it would be totally remarkable in the amazing if that minor specialty of physical time, say 1947 to the present, were the first and final corner of physical time to have a visit by extraterrestrial intelligence(s). The undeniable answer is that there have been past specialties in time, interims of time, most likely parcels and parts and loads of them, when ET visited. ET had billions of years to haphazardly (or specifically) investigate the (our) cosmic system. At 1% light speed it just takes 10,000,000 years to cross the system edge to edge. Yet, the cosmic system is ten billion years of age. On the off chance that there's loads of space-faring outsider human advancements, or regardless of the fact that there is only one, they are presumably a great deal nearer to us than the most dire outcome imaginable of edge-to-edge (clearly, since we're not on the galactic edge). The individuals who have contemplated this issue and did the math, propose that 10,000 to 100,000 years is an unpleasant assessment of time interims between arbitrary visits from ET. Still, 1947 to date could undoubtedly and most likely would on likelihood fall outside that range. Possibly the last irregular visit was 9,000 years prior, or 90,000 years back. Despite everything we'd have somewhat of a hold up (one thousand to ten thousand years) for the following call. However, and there's dependably a "but"...
