Ah! That must be in the narrows of your own mind, then.

Possibly, but we haven't seen such yet.

Trees don't move, yet they live and we detect them easily enough. I
dare say that if there were a giant which lived for 1 million years,
it would be visible whether it moved or not.

No. Only your limited knowledge and lack of imagination causes you to

Mobility is not a prerequisite for "life." Many life forms do not
move.
Structure is a prerequisite. All life forms have a finite extent, a
definite boundary between "self" and "not-self", and an identifiable
structure - they are not amorphous blobs of matter.
So is the potential for self-reproduction a prerequisite, or at least
the ability of its parent organism(s) to reproduce. If it lives, and
there was ever a time when it did not live, it must have started
living at some point. Except for the most primitive possible 'life
form' (which will always be arguably non-living) all life arises from
previous life.
So is mortality a prerequisite. If it cannot "die" can it be truly
called "alive"?
So is maintenance of its identity while interacting with its
environment to absorb and expel matter and energy a prerequisite.
