Aliens: On knowing we know not

To know that we know not could be a step in the right direction. 

Natalie Wolchover of Live Science takes this step when analyzing the many theories concerning extraterrestrials.

Wolchover states that we really have no clue as to whether aliens actually exist, let alone how they might look if they do.

They won't necessarily be "soft, squishy and big on mucus.”  Nor will they make it their immediate priority to gobble us up.  Who’s to say they could even digest us?

Most likely “immune to Earth’s bacteria,” they won’t succumb to the first microbe that comes their way. 

Contrary to popular theories, aliens are probably not our long-lost ancestors.  According to Stephen Hawking, they are more likely our future enemies. 

If so, they may attack us with AI technology, rather than with self-revealing methods.  Such invaders might never set “foot” on Earth.  After all; a civilization advanced enough to target us would probably instead send robots.
