Here's an example of traceability. If the god of the bible were real, eternal, unchanging, etc., there would be no historical record of him being just another god in a pantheon until someone decided to make him THE god. This is just one example of many and you can do this with any god in any religion - there's nothing notably special about Yahwah aside from how popular his worship became.

I asked because it's especially suspicious if you have been raised from birth to believe in a god, even if it wasn't a main focus. My intention isn't to dissuade you from believing - I couldn't do that even if I wanted to - but just to encourage you to see Christianity objectively, looking at its history and how it compares with other religions. If you choose to have faith regardless, that's fine, and in fact is stronger than if you never questioned it at all. I just always prefer that people make an informed decision on things.
