I personally never said that I think there definitely is no god, so that part is a straw man argument.
It is also not a requirement of atheism, as has been explained to you multiple times. Insisting that your definition is the correct one doesn't make it so.
Also, why is it not begging the question to say that it is out of our reach?
You say it's like blind people and colors, but that analogy doesn't work, because there are people who have seen colors, and can explain how colors work. Do you have a similar example for gods? Are there people who have "seen" gods, so to speak?
"I believe there is a god" seems less likely, given the evidence. It only seems equally likely if you arbitrarily put god above everything else. Something someone only does if they think it is important to keep the idea alive.
