We're call human because we are created in God's image and we possess some characteristics which makes us being different from other creatures.
Some characteristics which makes us different from other creatures are:
Language: this is the most unique cognitive which makes human being different from other creatures. Other creatures like animals might have have their own ways of communication but it's not a language, it could be refer to as sound. Some animals like parrot mimics human while talking but couldn't be refer to as their language because they imitate what human says.
Clothing: in this case human being can do without clothes to survive but due to shyness and cold weather human being can't do without clothes to protect their skin from physical attacks.
Knowledge: all creatures are made with knowledge to do one or two things but humans are created with more knowledge to do many things which other creatures can't do For example, the way other creatures uses the resources around them is totally different from how human uses theirs. Animals like monkeys uses trees as house and for games, human being uses trees for the same thing but in a very different and modernize way.
Shape and body: Only human being possess the same physical looking and suitable body for doing things other creatures can't do because of their body and shapes. For example, only human can use utensils and machines because they possess five fingers which enable them to hold utensils and machines.
Feelings: this aspect is what really makes human. Love, hatred, pains, sorrow etc are the feelings all human go through every day, and it's normal.
