Nobody can disprove what has been proven, obviously. Proof is everywhere that the whole world and all of nature evolved over billions of years, not less than a week. Mass extinctions including the biggest flood in world history are known to have occurred hundreds of millions of years prior to the existence of humans, especially homo sapiens - the last remaining species. I simply cannot for the life of me believe what the Bible says about the Creation and timing of the Great Flood, at least in terms of being the worst ever, is more accurate than what scientists discover. But in my heart I believe the Bible is God's Word and believe in miracles, so I don't want to feel like I am betraying Him in favor of sinners. Am I screwed up about my religion?
If you have already noticed, that Genesis covers a vast period of time. From the creation event up to the era of Moses.
In Genesis you have priesthood (Melchizedek), you have sacrifices, altars. Sin is in the world. We have the law given to Noah. We have covenants.
We have clean and unclean animals in the ark, Noah. We even have a rest day on the seventh day in Genesis. So it is highly likely that the text, was written by folk after the law of Mt Sinai. Unless of course the law was in effect before Moses?
We essentially have a problem in understanding what the purpose of this book of Genesis serves.
Is it a scientific journal regarding the creation of the universe?
Is it a strictly, historical record of every generation of humanity through history?
Is the book of Genesis, a simple religious account written for a very simple audience, thousands of years ago?
The Old Testament is wholly a Jewish text that grounds a Jew in their religious ancestry. The intervention of God in Israel's vast history in choosing, their nation as God's representative nation among all the nations.
So Genesis is compact, simply written, scientifically incomprehensible. Historically not accurate or even precise.
Noah's flood occurred but not a world wide flood.
Abraham existed and was chosen by God.
The genealogy is not accurate, the people mentioned may not be direct descendants, as in the son of preceding person. The Hebrew language did not have words for grandfather or even great grandfather.
The Genesis text is a summary, an overview, of Jewish history. For that purpose it was written. The Genesis text is also deeply symbolic. The tree in the center of the garden may not have been a tree at all. The garden may have represented something more pure. Be very careful when stepping through Genesis, a soft touch is necessary.
