[Correction: In my post from a year earlier, on page three of this topic thread, where I said "There are many Christians who are convinced that God does answer prayers (not just their own prayers, but anyone's prayers)" I think I meant to say "There are many Christians who are convinced that God does not answer prayers (not just their own prayers, but anyone's prayers)".]
Hello Nephilim87. I was raised from infancy as a JW, became baptized as a JW while I was an underage teen, was a regular pioneer for nearly 3 full years, was a ministerial servant for several years, and even gave some 45 minute long Sunday Public Talks in a Kingdom Hall. In about the year 2000 or 2001 I had major doubts about the WT and the JW religion and was burned out from the routine of the religion. I thus choose to become inactive as a JW (other than attending the Memorial and local JW assemblies and conventions for several years). That provided me with much more free time. I used much of that additional free time to read the entire Bible (and to study much of it), including the Apocryphal books
found in the Bible canons of the Roman Catholic, Greek Orthodox, and
Slavic Orthodox churches. I read all of it. I also read much of the book of Jubilees (it is part of the Bible of the Ethiopic Orthodox Church), all of the Gnostic Gospel of Thomas, portions of other Gnostic gospels, the Infancy Gospel of Thomas, and other books. To some degree I also increased my knowledge of of what scientists say pertaining to evolution.
Reading the Bible, and studying it carefully in a critical manner, contributed greatly to me ceasing to believe in Jehovah. That is because I noticed numerous problems in the Bible. Learning certain things (from a person in an online forum) about how the geologic record clearly disproves certain key things about the Genesis chapter one creation account and of the Genesis account of 'Noah's' flood convinced me that Jehovah/YHWH God did not inspire those accounts or other parts of the Bible. That along with earlier numerous things I had learned caused me to cease believing in the existence of Jehovah/YHWH God. What I learned of the geologic record also convinced me that Jesus was wrong to believe in the Genesis flood account and in the Genesis story of Adam and Eve, and that thus Jesus (whom the gospel book called "According to John" says made everything other than himself and God the Father) was not the son of God and not Christ.
Regarding the question of what evidence I was looking for from God after I prayed, I left it in God's figurative hands (if he existed) to reveal the evidence to me, evidence of a kind which he knew (if he existed) would convince me. I never became convinced again of his existence, nor did I become convinced that some other kind of God, such as a deistic god, exists.
But years later, for a number of days I was very nearly convinced that a deistic creator god exists (but not the biblical God nor any other alleged theistic God), due to me reading a book which I found out the WT had quoted form extensively in their Is There a Creator Who Cares About You? book (for a number of quotes of scientists). [I learned of the book as result of me making an intense concerted effort (after I had become an atheist) to discover the sources for the all of the quotes of scientists mentioned in the WT's Creator book (First Printing, copyright 1998).] The book is called Show Me God: What the Message from Space Is Telling Us About God (Wonders, 1), by Fred Heeren, and the WT quoted form the First Edition of the book (copyright 1995 or 1997). It is written by a science journalist who is convinced of the Big Bang theory and now also of biological evolution (with the biblical God playing a role in the process) and he also evangelizes for Christianity and he digs up fossils. The book interviews multiple scientists. The latter part of his book argues for evangelical Christianity. The WT does not mention the name of the book nor its author in the WT's Creator book. You might like the book. I seriously considered buying a copy of the latest revised edition of his book.
The book by Heeren severely shook my confidence in atheism and in scientific naturalism. I later regained my confidence in atheism and in scientific naturalism after I carefully read and studied certain scientific articles pertaining to the Big Bang and the rapid inflationary phase of the early universe, and as what existed before the Bang. One of the articles is published in Discover magazine. Other major factors which helped to me to regain my confidence were somethings I read in books by Victor Stenger regarding how an expanding universe makes room for localized order to come about despite the total entropy of the universe increasing.
I discovered the WT's Creator book quotes from a number of books authored by scientists who are Christians making intelligent design arguments in support of belief in God, and that in a few of those books the scientists also promote evangelical Christianity.
