There may be "advanced beings" out there, but...
I don't see any obvious evidence for them, and I sure as heck
ain't aware of their "benevolence" towards us, to say nothing of their
awareness that they know we exist.
Without evidence, such beings remain speculation.
This is the major difference between faith and science.
I am pretty sure there is extraterrestrial life, based on what we know
about the Universe through science. Even Rare Earther guys like
Peter Brown think the Cosmos is full of planets with at least simple
life forms on them. But until some solid evidence comes along, the
concept remains a concept, not a solid fact.
