Dear Vince,
I have similar feelings than you about how Jehovah is portrayed in the Bible. I could never understand the many contradictions that a god of love would order genocide, even ordering babies to be killed. That brought me to the point, that I believe Jehovah is "just" the tribal god of Israel. Moreover I studied a lot about the flood account. I came to the conclusion that it must have been a local flood (see Pitman and Ryan Black Sea flood) which is not at contradicting the bible account (just the wt view).
That path led me further to investigate radiometric dating methods and proof of human life before bible chronology (chauvet and cosquer cave paintings go back to 30000 years).I tried to find ways of harmonizing this with the bible account. That is not easy but might even be possible.
For the first time (grew up as jw) I studied evolution without any prejudice. I came to see that a lot of the theory of evolution is based on facts but most importantly is misrepresented by wt. I realized that a "theistic evolution" does not even contradict the genesis account.
After studying all of this I did not become an atheist. I strongly believe in a creator. I don't know how or what he is but for me I still believe he is also a loving creator. Life is a mystery and I believe there are many things we are too small to grasp and we should be humble enough to admit that (not like wt who makes wrong scientific statements and acts proudly)
