Yes, Adam was the first man. Genesis 2:7,8, "And the LORD God formed man (the Hebrew word is Adam) of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. And the LORD God planted a garden eastward in Eden; and there he put the man whom he had formed."
Adam was a special creation because he was created in God's image. Genesis 1:26, "And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth." Adam did not look like God. He was like His wonderful Creator in that he could reason, be just, love, and exercise benevolent authority. God made man in His character likeness and put him in charge of managing the earth.
