God made Adam, the first man, from the dust of the ground (Gen. 2:7) and He made Eve to be a help meet for him. People lived much longer than they do now; the oldest man in the Bible is Methuselah, who lived 969 yrs (Gen. 5:27). The Flood came in Noah's days because man was doing "only evil continually"; so God saved only Noah and his family because "Noah found grace in the eyes of the Lord" (Gen 6:8). We also see in Heb.11 that Noah was a preacher of righteousness. That's only a little bit; try reading Genesis to get all the info you need about early man. I hope this helps you!
