There a number of biblical passages (such as 1 Corinthians 4:9) that are worded as such indicating angels were created separately from and and are different from humans.
For it seems to me that God has put us apostles on display at the end of the procession, like those condemned to die in the arena. We have been made a spectacle to the whole universe, to angels as well as to human beings. (1 Corinthians 4:9, NIV)
From time to time I hear someone talking about their deceased love-one being an angel in heaven. I see this in works of fiction on TV and the like too.
Is there anything in the Bible that suggests humans can become angels?
