In my viewpoint, it is impossible to prove the existence of the Christian God in a factual and verifiable way because doing so would necessitate someone having infinite knowledge and power in order to be present everywhere at once, which is not possible because humans are not omniscient, omnipotent, and omnipresent. Furthermore, any claims such as "God saved me and changed my life," "I know God is real because I called out to him and he answered," or "I know God is real because I feel his presence in my life" are all anecdotal evidence and should be taken with a grain of salt. I don't believe anecdotal evidence is reliable enough to prove or disprove the Christian God's existence. This is the reason why, when it comes to the existence of this God, I am now an agnostic rather than an atheist. In my opinion, I cannot provide empirical and verifiable evidence that the God of the Bible does not exist, just as when I was a Christian, I could not provide empirical and verifiable evidence that God exists. As a Wiccan, I believe in multiple gods and goddesses, but I cannot prove beyond a shadow of a doubt that these deities exist. It's simply what I believe, and it's anecdotal evidence at best.
