I guess asking an atheist about god is like asking a blind person about the color blue. Amazing, I never thought of that. That's exactly right (more right than the invisible one since no one can see the invisible but people can see God)
If You are blind and of course as long as you are you might make all the effort you want you will never be able to see blue. It doesn't mean that blue does not exist!
Same thing with God.
Thank you for the comparison. I love it.
You are very welcome, Lukvance.
You are consistently a most polite and endearing theist, even as you exhibit the most ignorant, obtuse and frustrating communication style I have ever encountered on this board. Jst and skeptic should send you money for making them seem so much more reasonable by comparison. If I believed in saints, I would nominate Old Church Guy to replace that nasty piece of work, Mother Teresa.
Even though I have you in ignore mode because dealing with you is too much like revisiting my years as a social worker, I still interact with you. Despite my lack of faith, I still have hope. 
I assume you understand that you could never argue
a blind person into "seeing" the color blue, let alone the color invisible. (And actually, the color invisible is a more accurate analogy than blue because nobody has ever seen a god, while people have seen what appears to human eyes to be blue. How can anyone see something immaterial, invisible and supernatural?) Imagine someone beating up or torturing a blind person into seeing colors. No matter how hard they try, the blind will never be able to see any color--blue or invisible or whatever-- it is not possible for them to see it. They will finally say they see blue, or even invisible, just to get the torture to stop, but they will be lying.
Given that we atheists cannot sense any gods and are basically "god-blind" (and "god-deaf", etc.) you cannot hope to argue or logically trap or browbeat us into believing in any gods. All the societies that have persecuted and tortured people for not believing in a particular god, for questioning religious ideas, or for being atheists have been basically beating up blind people for "refusing" to see the color blue or the color invisible.
Lots of people have been beating up on the blind for not seeing colors: Catholic countries with their history of mistreating non-Catholics or dissenters by purges, elaborate tortures, imprisonings, inquisitions, burnings at the stake; Muslim countries with official state religions, apostasy laws and death sentences for atheists; Hindu India persecuting Muslims and Sikhs; Christians--both Catholics and Protestants in the Americas forcing their religions onto the indigenous folks; everyone kidnaping and enslaving people, then making them accept a foreign religion, and on and on. 
I hope you also realize that, unlike the people who beat up on the blind, we atheists generally do not try to force other people to not
see the color invisible, even though we don't see it. If they say they do, so be it. Just like the blind person can acknowledge that other people see colors out there, even though they themselves can't see them.
We atheists can find no evidence of any color invisible (gods), but most of us will acknowledge that there is a possibility that there is some sort of god out there, somewhere. What we are saying is that the gods that people describe to us do not seem to be real. The stuff people say that gods do, seem to have other more likely explanations. Down through the ages, people have continually discovered better explanations--with far stronger evidence-- than gods for all sorts of things, over and over again.
What we are trying to do is get religious folks to only apply the same standards for their belief in gods as they would to a new recipe, a brand of toothpaste, a headache pill, a pair of running shoes, a cell phone, a car or any household appliance. What people who believe in gods call evidence is lame and weak and does not pass as evidence in other areas of those same people's lives. Nobody would accept a 2% success rate (98% of the time it fails) or even a 20% success rate for a brownie recipe or a cell phone. Why accept a rate like that for prayer, as if it does not matter that an all powerful, loving god fails 98% or 80% of the time, requiring people to make excuses as to why they have to take care of whatever themselves?
And if the rate of magical success is really high enough to warrant belief in a supernatural god, it should be easy to demonstrate it with simple scientific tools. Just like a car or a headache pill. It works or it doesn't. No fancy dancing or excuses.
