Peace Light,
This post is concerning the story of Harut and Marut. What I had written was one opinion, but the strongest opinion is that they were angels who were commanded by God to come down to Earth as a trial for the people of Babil. They had told the people not to disobey God and not to follow them as they were only there to test them as is stated in the Quran. The people had made magic their religion and so it was only meant as an assessment for them to see their level of obedience to God Almighty.
As I had already mentioned, there are many opinions on this, but as Muslims, we should follow the strongest opinion which have the most authentic evidences!
I had also come across one Islamic book which claimed that they were not angels but men
