It is best to pray for understanding while reading the Bible.The world doesn’t make any sense right now. Read back in Genesis when God first created the world and Adam and Eve had it made in the Garden of Eden. Perfect weather every day. No sickness. No politics, taxes or I-phones. You could walk up to animal and pet it. Well, that didn’t last long. Sin ruined everything. It is getting to get worse.
The Bible doesn't say how long Adam lived in Eden. Could have been a month. Could have been a thousand years.
