No, Adam and Michael the archangel are not one and the same. Let’s use the Word of God to see how we can know that.
Adam was formed of the dust of the ground, and God breathed into his nostrils the breath of life. Michael was one of millions of angels created by God — just as was Lucifer.
Adam could procreate (have offspring). In fact, he was commanded to fill the Earth with children; Michael could not as angels are unable to bear children (Matthew 22:30; Mark 12:25).
Adam was called a man. Michael is identified as an archangel. The differences are clearly distinguished in Scripture. Man was made “lower than the angels” (Psalm 8:5) and will one day be higher than the angels (Hebrews 2:7-8). Man will judge the angels someday (1 Corinthians 6:3).
Angels are spirits; man is flesh and blood. Angels are called a company, but never a race. Angels are greater than man in knowledge, but they are not omniscient. Angels are much stronger than man but not omnipotent (neither Michael the archangel [Jude v:9] nor Satan [Job 1:12; 2:6] has unlimited power).
Both man and angels did sin at some point. The Bible is not clear as to exactly when they fell, but one thing is certain: Angels sinned (fell) before man did. We are told that Satan entered the garden in the form of a serpent and beguiled man.
Another clear difference between man and angel is that God died to redeem man to Himself. The angels that chose to follow Satan in his rebellion against God have never and will never be given an opportunity to change their minds. Their choice was made in heaven, in the presence of God (imagine, sin originated in heaven), and thus, they can never be saved by grace through faith.
So in answering whether Michael the archangel and Adam were one and the same, we also seemed to prove that Adam and God were obviously distinct as well.
In the beginning, God created the heaven and the Earth. Thus, the Ancient of Days was not an angel; He created the angels!
Adam sinned, but God cannot sin (Hebrews 4:15; 1 John 3:9). Stop for a second and consider that. The God of the Bible cannot sin. He cannot lie. He has no room for improvement.
Often the god that man creates is demanding and insatiable. For example, some gods demand that you prove your love for them by killing in order to please them. The one true God of the Bible, however, has instead proved that He loves you by dying for you in your place as your substitute.
If you have not already, please believe on the name of the Lord Jesus Christ. He is the only begotten Son of God. He is the Messiah of Israel and the Christ of God. And He is your one and only means of forgiveness (and, yes, you do need to be forgiven). For God so loved the world.
