Justifications are excuses and you know you're finding excuses when you're digging through minutia to get the answers you want to make you feel better about whatever is distressing you. The simplest way to recognize whether or not you're using excuses rather than sound reasoning is if your answer is a catch-all with little to no questioning involved. It's often circular logic. The largest perpetration is peoples' use of God as an catchall answer to everything they can't answer themselves or which all world societies haven't collectively found the answer to.

God is a cultural answer and a personal truth, not reality. It may be reality for many, it may be your reality, but it's not the reality because we can't find a commonly discernible evidence for the existence of such a specific creature. In science, conditions must be replicable across the board to be proven correct. No absolute evidence exists everyone can clearly agree on. Speculative evidence isn't factual evidence.

You can't point to a source itself to prove itself. That's like saying superman is real because he's in this superman comic I read. See, it's right here, what have you to deny?

It's faulty and convoluted logic.

Perhaps the most identifiable reason God doesn't exist is the simple universal truth that if something is too good to be true, it probably is, and it usually is. Religious people view reality from their perspective, not from the worldly perspective that comes from living among other people in other nations of different minds and histories. Everything up until now has been mythos, so what's to make Christianity so special that it too isn't the same? That's a serious question that needs objective third party sources to answer and verify.

The truth is that none of us know best. We're on this planet less than a hundred years. What's to make any one of us think we have the answers? it's arrogant and foolish. A lifetime isn't enough, probably not even two, to claim you have the answers. Don't assume you understand what's best for others just because you understand what's best for yourself.
