I like it, cuz I see your point entirely, but you fail to see that science is still subjective, it is the analytical mind at work. By the way atheism is an argument from ignorance, all though I do love the quote about open mindedness, and all of the others, an open mind is required not to neglect possibility by assuming probability as absolute truth, this is why I'm agnostic.
The scientific method itself is purely objective. Humans may make errors of bias or subjectivity, which is why all serious science goes through the process of peer review: to provide checks and balances for any subjectivity that tries to seep in. It seems like you will eventually learn how science actually works. Atheism is not an argument from ignorance, it is a rejection of all the specious positive claims that are made concerning deities. Atheism addresses
belief, not knowledge. Atheists do not say that there is no creator, they couldn't possibly know that because there is no way to look everywhere in the cosmos at once. Atheists are claiming that they lack belief in a creator. There is a small subset of atheists that claim that there is absolutely no gods, but they are relying on faith as most theists do. Agnosticism is a question of
knowledge, not of belief although modern vernacular has hijacked the term from Thomas Huxley from what he originally meant. The possibilities are -
Agnostic Theist - One who believes in god(s), but realizes he cannot know if one exists
Gnostic theist - One who believes in god, and claims absolute knowledge god exists (this is most theists)
Agnostic Athiest - One who lacks belief in gods, but realizes he cannot know if one exists. This is most atheists (and me)
Gnostic Atheist - One who lacks belief in gods, and claims absolute knowledge god does not exist (only Pad IME)
To know whether or not you are an atheist, ask yourself if you believe in a god. If the answer is anything but yes, you are an atheist. If you realize no one can know for sure, you are also agnostic...
