It certainly is. Your attempt to redefine words isn't going to work. Semantics fallacy.
Agnostics are the honest people, those who admit we simply do not know.
Here I would agree. They simply do not know the character or form of any god or gods.
I've seen no evidence supporting the idea of a god or gods.
It exists. See the Bible, the organized factors in nature, personal testimonies of people on the effects of a god or gods, the Earth itself, etc.
Nor have I seen evidence precluding the idea of a god or gods.
It exists. See conflicts in the Bible, nature (as explained through processes that do not involve any god or gods, the existence of the Church of No God, etc.
I know for a fact that the Koran is crap, the Torah is crap, and the Gospels are crap.
Not facts. An opinion. Learn what 'fact' means. It does NOT mean 'universal Truth' nor 'proof'.
A fact is merely an assumed predicate between parties.
Since your statement assumes the predicate between everyone, you are attempting to speak for everyone (omniscience fallacy). There ARE people that believe the Koran is True, or that the Torah is True, or that the Gospels are True.
All you know is your own opinion here.
The bhagavad gita is laughably childish, primitive.
Another opinion.
Even so, we have no ability to understand, much less explain the marvels of the quantum universe.
The universe isn't quantum. Quantum mechanics isn't the universe either. It is simply theories of science.
What we know is a molecule in an ocean, limited and driven by our physical perceptions.
Science isn't 'perceptions'. It is not observation or the data created by such observations. Science is a set of falsifiable theories.
The study of perception, observations, and the data resulting from them is a branch of philosophy known as 'phenomenology'. This branch also defines words like 'real' and gives the reasoning behind such definitions.
Only a fool would claim that we can preclude the ideal of a greater intelligence.
Calling most people a fool doesn't help you. Every religion (even fundamentalist ones) DOES have a reasoning for it, even if it is based on faith. Many of them wander into various fallacies (fundamentalist religions commit a circular argument fallacy by definition), but they ALL have reasoning for them.
We not only don't know, we lack the ability to know.
This is correct. It is not possible to prove the existence of any god or gods, and it is not possible to prove that no god or gods exist.
