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.

Done and done.
I think honestly humanity is being squandered by income inequality. Imagine if money wasn't an issue for anyone. Imagine that we had a HUGE appreciation of science so much so that 90% of kids grow up to be scientists and explorers.
Surely that would get us to have higher and better technologies and also get us further in space flight. But instead elites would rather the potential scientists of the future 'know their place' and remain there in poverty never getting a degree/etc...

Frankly, I don't think these videos alone are the highest quality evidence of this kind of thing, but they are interesting because it is difficult to dispute the credibility of the witnesses and the timeline of events described by them. Usually you get some tangible evidence (video) or solid witness testimony, not both at the same time.
I've never clearly seen anything with my own two eyes that I couldn't explain in prosaic terms. However, I know groups of people saner than I who have, and science suggests its highly improbable we are the only planet with life [0], let alone the first one to evolve a sophisticated civilization. People come up with Great Filter hypotheses and what not to compensate, but considering we may be less than a century from self sustaining space stations, that hypothesis is running out of air for its only known test trial.
It kind of sucks to think we don't really have manifest destiny with the universe, but the burden of proof is on the skeptics to prove there are some really damning parameters for the Drake Equation before saying it is so unlikely that there are aliens in our neighborhood.
