The “science” approach was appealing to me. But science has never even had a concept for what was there before the “Big Bang.” Science ultimately places its understanding of the Universe on faith that everything just “is” and that there's an explanation, but we just don't know it yet. Unfortunately, no scientist even has a concept for what happened before the situation that happened before the Big Bang happened. And for each step further back, “science” has never had a clue for any of it. Just a simple “we don't ask such things here and we sure won't ever have those answers.”
Then I was left with thinking that God must have made the Universe. But then, what form was God? This led me to look at various religions, as I surmised that God would have likely wanted us to be here on Earth if we existed and were sentient creatures. Subsequent to that, I looked at various religions, both ancient and recent.
In short, many religions didn't seem to hold up. However, strangely, Christians, Muslims, and Jews all agree that the original “Old Testament” books were, for some agreed reason, legitimate. So the books of the Jews seemed validated by the most entities on the planet. However, in reading those and understanding how Christianity and the Muslim faith came to be, only Christianity seemed valid, so it was this and Judaism. However, Christianity specifically validates key parts of the Jewish understanding from their own books, and even Muslims believe Christ was a Prophet, while Jews generally regard Jesus as a wise man, but not the Son of God.
In the end, a strong, conservative belief in God through the Bible was the only resulting belief left to hold.
