OR is a scientific methodology in arriving at the best hypothesis given a set of circumstances. It doesn't necessarily explain phenomena or resolve a mystery or the unknown.
What 'competing' hypothesis would you suggest for that video I posted herein (also, not the best one out there for actual unidentified flying objects)?
(Note: I would agree that you can't conclude incontrovertibly that those 2 pulsating lights travelling in tandem are extra-terrestrial visitors but WTF?)
Actually yours is the reverse logic used in conspiracy theories.
As far as our best understanding of science:
- probability of life in the universe exists but is very low which means
- any alien life is likely a very far distance away and therefore
- it would take a ridiculous amount of time to travel from there to here and
- aliens would either be visiting every single star in the Universe or for some reason have decided it was extremely important to visit us (even though there would be no other way for them to know we're here).
So for aliens to have visited us, they would have to exist in some place near us (in universal terms), they would have to have technology far in advance of ours which would allow them to travel huge distances, they would have to have some reason want to visit us, they would have to decide that they want to hide from us but despite their advanced technology are unable to completely do so, and they would have to decide that for some reason we should destroyed, conquered, colonized, or otherwise harmed and that they shouldn't interfere in the stupid things we are doing to wreck our planet.
To me a hoax or a misunderstood 'normal' occurrence seems like the far far simpler and likely explanation.
