Gosh, give me a little credit here and assume I have something in mind that goes a little bit beyond the above....I'll try to keep this short...
The "burden of proof" question, and the "proving a negative" question, are both relative to the discipline...and there are several to choose from...
For example, within science the common practice is to place the burden of proof on the one making an assertion, and more importantly, science doesn't generally make claims about nonexistence. i.e. a scientist will say something like "well I doubt unicorns exist because we've looked around the globe and we've yet to find one. I can't prove they don't exist, but I have no reason to think they do, and I seriously doubt they exist".
In mathematics the practice is quite different. The burden of proof remains with the one making the claim, but proofs of non-existence are common practice and quite valuable. Something, say, like "prove that a smallest rational number greater than 0 does not exist".
So in response to your statement that "As a life long atheist without a single second of doubt " I'd make the following observations.
First, such a statement would have to be bounded by the method which generated it. For example, you might say "from a scientific view I can state God doesn't exist" or "from a purely logical view, and based on the following assumptions, I can state God doesn't exist". You don't do this, and so what seems like a simple and direct statement at first turns out to be ambiguous.
Second, if this statement is indeed meant to be scientific, then it overreaches because this kind of scientific claim of non-existence, like claims about the unicorn, have to allow for at least a tiny fringe of doubt. But you don't allow for any doubt at all...so you are going beyond science.
Third, in the realm of logic (mathematics is, by the way, a species of logic) a proposition's value remains unknown unless it is proven true or false. When it comes to the the proposition "God exists" theism corresponds with "true", atheism corresponds with "false", and agnosticism corresponds with "unknown".
So if your statement is meant to be logical (formally rational) then you are making an assertion that needs to be proven...in this case the proposition is "God exists" and you are asserting a value of "false" rather than the default of "unknown".
Where I am steering this is as follows. If you are saying "As a life long atheist without a single second of doubt in 30 years", and you will really allow for no doubt (i.e. it's not established by science), and you really see no need for logical proof (i.e. it's not established by formal logic)...then guess what? You're simply relating a breathtaking leap of faith on your part.
I'd invite you to reconsider your position and jump ship to the agnostic camp.
(Arrrg...my apologies....I accidently edited this post rather than starting a new one....I've restored it here again though ...
