"If some life form has developed a way to get here, they are using technology that no one on this planet has even dreamed of, which means they could come here and not be detected."
My personal opinion is that once a civilization develops space habitat technology, they cease to be planet dwellers, mining the Oort clouds of stars as they diffuse across the galaxy.
Why bother with planets??
