You're right I don't know anything about Occam or the origins of the razor. I wasn't claiming the razor as something originating from atheism. Rather, I was saying that atheism is bolstered by the razor.
I'll take your word on faith>knowledge but don't understand why you're saying it.
Do you have thoughts on what I said about your assessment of atheist simplicity and arrogance?
Atheism isn't bolstered by the razor, because the application isn't applicable to Christianity or theism. The disposition atheism starts off from isn't from the complexity that arises with religion, it starts off from the self. One would be fooling themselves if they thought they were starting off with something that they perceive (of from themselves). It hardly comes from a birds eye point of view, most of the time it's an inheritance of a secular mindset, or a fractured worldview when they see Christianity and the world together side by side. There isn't a smooth relation- which is actually the church's fault, but nevertheless, to Christians, the truth, to us, still stands.
Think of it this way: if God created the world, and one uses the "razor", what is the more easier answer? Going through the theories of abiogenesis, of the big bang, of other cosmological theories of the beginnings of the earth; the universe? I would just go with "God made the world" in that case, because the razor would slice away the complexity. In a sense the razor seems to bolster theism more than atheism, to me, if one thinks it through.

The error I see in a lot of people who espouse to be atheists is that they have a certain confirmation bias when it comes to the existence of God. Ultimately it comes down to epistemological error, that since we cannot tangibly interact with God, he must not exist. That's where the misconceptions start, because that person is unaware of the theology of God, or what God really constitutes. The razor isn't applicable to theology because it's more of a haphazard application of something which one does not have a clear understanding of. If the premise and the subsequent matter were to be established clearly, then maybe the razor would work, but it seems the application you've been espousing is more haphazardly applied rather than thoughtfully considered.
On atheistic simplicity and 'arrogance', not really, because Christians too are half atheists, to a degree. Christians have doubts too, which on a mental level or plane, is the same with what atheists have/live through everyday. There isn't much difference between an atheist and a Christian, Christians just simply believe, or have faith in, one more God. We all eat and shit, go to sleep and make love to our wives, (or husbands), etc, work and like going on vacations, and so on.
