All logical explanations we have from a scientific basis are from our own scientific research that has been made possible given our current equipment and technological advancements as human beings. Pretending that we are the be all and end all of possible intelligence would automatically lead someone to discredit even the slightest chance of another intelligent life form out there. I don't for a second believe we are the only species in existence in the universe who have intelligence and I can imagine there is something else out there that may have technology and intelligence beyond what we can imagine, so anything is possible. At the end of the day, to automatically discredit any theories like this will forever leave us in a position to assume we know all there is to know about the universe, and the means by which there is to continue learning and discovering new things period, for that matter.
Anyway, I'd love to see an alien spacecraft do some Independence Day style damage on some specific people before I die, not gonna lie.
