They all saw things in the sky or near the ground that were completely unexplainable... (Little Hawk)

Still making the same language terminology mistake year after year even if it has been pointed out to you (and acknowledged by you)?

Unexplainable: It cannot be explained in terms we are...

That neither them nor you can know for certain.

(Yet) Unexplained: waiting for an explanation in terms...

That someone sees something she cannot explain in terms..., does not imply that it cannot by explained in terms...
