And by aliens I mean, outer space creatures and UFO. For whatever reason all UFO sighting footage looks either fake or like recorded with a Casio keyboard. And I find hard to believe we don’t have any decent footage of them with all the surveillance and technology we have now.

It’s very unlikely, given the lack of evidence, and the immense technological base requires to make it across the distances required to get to other systems. The physics of the universe as we understand them alone is a massive mark against the possibility.
