How can my belief be so strong?

[Tonus]

I often find myself wondering why my faith is so strong. I call my belief that there are no gods a faith as I lack any better verbiage to describe it.

There could be any number of reasons why. Perhaps it is psychological. A very confident and aggressive person may not be willing to accept doubt in a position and prefers the absolute because he feels he can convince/compel others to see it his way. Others may simply feel it's the more rational approach. The common example of creatures of legend may be waved off by some, but there are many such things we regard as myth with no doubt whatsoever, and few people (theists included) will say differently because they feel the same way.

It may also be an indicator of our deep desire to know things for sure, to have closure. Humans seem to truly hate not knowing, not being sure. We have to know. We have to have the answers. We do not like waiting to find out, so we will accept whatever we have at present and accept that. "God absolutely does not exist" may be an ironic example of a "gaps" argument.

I believed in god for many, many years but could not justify that belief, and trying to do so left me with the realization that he was not there. Can I prove that? No, I cannot. But the more important thing for me is that, for more than 2/3 of my life, I tried to prove that he DID exist. Failing that, I accepted that he doesn't. If the closest anyone can get to convincing me that I'm wrong is to say "you might be wrong" then I figure they're only a step or two away from where I am now.
