That's a big "if". If magic exists, then maybe Gandalf is real.

That there are new things to discover there is no doubt. I don't know how it relates to your need to believe in ETs visiting Earth, but rest assured we have plenty of things to discover about the universe. Most things we will never know.

What's tragically unscientific is cherry picking reports (sometimes by people who are not even claiming the final implication you'd like), disregarding the obvious implications (hoax, liars, top secret military tech, etc) and jumping to conclusions.

What's tragically unscientific is not understanding the scientific method and that extraordinary claims require extraordinary evidence.
