While I certainly see what you are trying to do, it is not the same thing as belief in God.
You may be right that there is no definitive way to 100% prove that Santa doesn't exist, but this means that you believe Santa is not real. You probably believe a lot of things are not real. That is fine.
I just find it shocking and odd that the atheists don't just call it a belief. There's always all these word games and semantics to get out of saying that it is a belief.
Try to see it from the theistic point of view for a better understanding.
No, seeing it from a theistic POV is NOT better
. It is worse b/c you have an assumed theology that you are attempting to force everyone else into. We simply LACK belief in things like Santa Claus, Unicorns, and Yahweh. But due to the fact that you view these things as inconvenient to your assumed theology/worldview you refuse to accept them. You keep trying to make unbelief (or non-belief) into
belief. They are NOT the same and they are mutually exclusive. If YOU just so happen to believe
(for example) that there is no Bigfoot, that is on you. But that is NOT non-belief. Many of us here are trying to educate you on the difference. We LACK belief in Bigfoot and that is not a belief!
Do you understand this difference? Leaving open the mere logical possibility (regardless of how small) for Bigfoot to be shown, we do not accept the current claims. Again, this is not the same as having a belief in the non-existence of something!!!
We withhold judgement (i.e. - lack belief) until further evidence comes in which may or may not change perception. That is the intellectually honest position. You don't know if there is no Bigfoot, and you likely don't know if there is one
either. The same goes for space aliens. There might be, there might not be, but we lack belief until sufficient demonstrable evidence arrives!
This is what you keep failing to understand, and it is based in your credulity/gullibility. You have this virus in your brain saying, "We MUST have an affirmative answer RIGHT NOW!! You must choose!!!"
But we don't have to choose (and belief is not a choice anyways). This is a completely false assumption. You do not
need to make a determination right now, but for some irrational reason you choose to assume that you do. And hence, you have found yourself in this mess of believing (at the outset) the words of old credulous and fearful men - heavily filtering everything through your assumed theology. That is confirmation bias and it fails b/c it is unreliable for separating fact from fiction. It fails for every other religions assumptions including yours.
