When you compare Human DNA to that of a Banana it has 50% similarity. That is always so because 50% of life is Fauna, 50% of life is Flora, and both are alive. That 50% is the basic of life. We need both fauna and flora to be present in order for this planet to even have oxygen. The rest of the changes is due to evolution. Evolution is the greatest story of God. But how, when, where and why God caused Genesis is unknown. I believe firmly that God only creates and then only instructs. Listen, why would something we consider the infinite, create a set amount of vessels. Isn't it more beautiful for the Infinite one to create just one thing and let it evolve like it wants to evolve? So that everything is unique? Look what dwells here, all from just one ancestor. If you are smart you can see that survival can be an endless loop. But, DESIRE.
You can read the book and live by it. You can do everything right in a book. Everything by the dots. And then stand before God, ready to be judged. And then he sends you straight back to earth with no memories. Here you got another vessel, have fun.
