The jump between space stations and interstellar travel is huge. I agree that it's improbable that we're the only planet with life, but being visited by aliens is as, if not more, improbable.
Consider the age of the universe, our (humanity, with the ability to apprehend the existence of alien life) existence in it is but a blip. What are the odds that one or several forms of life capable of interstellar travel exist during that same time period, not before or after. That alone, among myriad other reasons, makes me pessimistic.
- postalrat 6y agoIf they are sending out probes how long do those probes remain active? Can they repair themselves or build more on their own? I assume that is what we would be seeing.
- incompatible 6y agoWouldn't they have been easily observed by now, perhaps even making contact? Unless they are deliberately trying to remain unobserved, in which case being caught on video from an aircraft seems careless.
- gremlinsinc 6y agoWe should create message bots and probes who basically explore far reaches of space and categorize data, send it back to all other nodes and essentially make as detailed a 'map' of life/discoveries/etc so that not only we could use it benignly but so could other species who come after us. Assuming they could figure out and translate/understand how we categorize it.
