Sure, it is creation. The definition has never been limited to God's creative work. Since we are made in the image of God, we are also creative. Artists, architects, designers, chefs, a child with a package of crayons, they all create. The one difference is that humans are limited to creating out of materials which already exist while God is not. But God also creates from what already exists: he created dirt and then created living things from dirt.
No that would define "miracle" not "creation". And it would limit God to working via miracles, something scripture does not do. God works both through supernatural and natural means.
Why not "something new"? That is biblical. "Behold I make all things new".
Each species, even each individual is something new and unique. That is why we can speak of God creating each and every one of us.
