Unsupported - and projection.
If you are an atheist you have because thats what atheism is.
And thus rendering atheism an argument from ignorance and atheism and yourself irrational and illogical.
Shifting the burden.
Yes contradiction because you claims you dont know then you claim you know
Again contradiction - how do you know the universe and your very life is not that evidence?
Shifting the burden
So you cannot know it was natural thus you contradict your self AGAIN with your " I've seen no evidence of the supernatural during my lifetime" - if you dont know then you cannot know you have not seen evidence for the supernatural.
No that is not the sole definition of Atheism as you well know.
Again I have not made a claim so no argument from ignorance.
You are dodging the question.
Again I haven't made a claim.
Can you show me that the universe and my very life are evidence of the supernatural?
Again you are dodging the question.
If you can tell me what parameters to use to evaluate supernatural intervention I will gladly re-examine my experience.
Until then you've given me nothing to work with.
