Are we considered creatures or are creatures only bugs and unidentified life forms?

"Creature" is from the future participle of the Latin verb for "create", so any created thing is a creature, technically.  It's mainly synonymous with "organism".

Genesis 2:7 

And the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul.

Everything living can be said to be a "creature". Look up the word, and see for yourself.

I think we are all creatures.   Some people may use the term for animals (including bugs) that they do not know the name of, but all forms of life are creatures.   Bugs, identified animals , unidentified animals , and humans.    Even alien space creatures.

I think creatures comes from the word "create" and no matter what view of life you take, we would be creatures like the animals
