Adam and Eve made the decision to disobey God's instructions. As a result, He expelled them from the Garden of Eden.
Not long after our first human parents' experience in the Garden of Eden, people began to replace the veneration of God with their own forms of worship. They quickly degenerated into idolatry by willfully rejecting God's laws. As with Adam and Eve, they, by their actions, rejected a close relationship with God (Genesis 6:3-7 Genesis 6:3-7  And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.

Notice where Paul places the blame for the breakdown in the relationship between God and man. "For the wrath of God is revealed from heaven against all ungodliness and wickedness of those who by their wickedness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. Ever since the creation of the world his eternal power and divine nature, invisible though they are, have been understood and seen through the things he has made. So they are without excuse" (Romans 1:18-20 Romans 1:18-20  For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness;
 Because that which may be known of God is manifest in them; for God has showed it to them.
 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:
