Can we get to the bottom of this before you start assuming fallacies? many times when someone is claiming a fallacy it's because maybe they're not seeing the rationale, missing the argument. I get what you're saying but somehow I don't think you're getting what I'm saying. I'm no longer arguing that an atheist cannot believe in what we've been talking about that's no longer the issue. The issue I'm bringing up is the foundation (worldview/conception) of those beliefs, and that if you say God did not create the universe then that means everything that began to exist exists without the need for God, it began by natural means and there is a term for that. If you believe that God created the universe then we call that creationism, the only other alternative to creationism is naturalism/materialism, meaning that the universe began to exist without God through natural means. Philosophically I'm unaware of any third premise, which is probably because there's only two choices, this is simple logic.
Now before you go and repeat yourself again, would you agree that God either created the universe or God did not create the universe?
I don't care personally if there's an atheist out there who believes in spirits and alternate dimensions, it's nonsensical but it's not the point I'm making. It's much like believing that a football belongs on the basketball court lol....sure we "could" play basketball with a football but it would be somewhat stupid right? because we're using the wrong medium to be on that court.
Perhaps don't be so stubborn because you don't want to be wrong and just realize the simplicity of what I'm getting at. You don't want the atheist to carry the label materialism I get that, why you're adamant about that is somewhat weird. Why don't you create a pole and ask atheists on this site how they understand how the universe began and then we can evaluate their clams? because at this point the conversation is getting silly, so maybe it's better if we just see what they say themselves.
If there is an atheist that pops up and says they believe in other dimensions, spirits and ghosts I'll put the same questions to them. Only in an attempt to show which category their worldview falls under.
I'm not being close-minded here, not at all I'm just using commonsense and you've given me no answer or reason to believe any other conclusion. Saying "they don't need to know what created it to believe it" is avoiding the issue...because there's only two options. And an atheist only falls in one of those two options whether it's apart of the definition or not.
Materialism-
is a form of philosophical monism that holds that matter is the fundamental substance in nature, and that all things, including mental states and consciousness, are results of material interactions. According to philosophical materialism, mind and consciousness are by-products or epiphenomena of material processes (such as the biochemistry of the human brain and nervous system), without which they cannot exist.
Creationism-
is the religious belief that nature, and aspects such as the universe, Earth, life, and humans, originated with supernatural acts of divine creation.
