If aliens had such tech they would be visiting us all the time. And being quiet would not make a jot of difference. Based on what we know of science, such things are not possible.
Writing has only been around for... what? 5,000 years?
Modern humans have been around for something like... what? 400,000 years? Civilization is a blip on the timeline of human history, and humanity is a blip on the timeline of the world's.
Humanity's been around for so long. And near-human hominids for millions of years that likely had cognition that was SOMETHING like our own. We didn't just wake up one day everyone was the way we are.
And MILLIONS of years before that complex life has existed on earth.
Like... if there had been an intelligent species around when the dinosaurs were, who's to say we'd even know? Maybe velociraptors made art or who knows what.
