Argument against atheism

[Perhaps]

For those who believe that proving yourself is possible,

Try this....raise a hammer high over your head and bring it down as hard as you can on your other hand.

Let me know if it hurts or not.

So consciousness defines existence? My ability to perceive pain proves that i exist? Then what of non conscious bodies? Do we determine they exist based on our conscious decision? What then of subjectivity? Surely existence becomes subjective if we allow it to be defined by consciousness.

You see how slippery this slope is? We try not to fall off, so we assure ourselves that we exist - we make it an axiom - but the 'fact' of the matter is that we cannot definitively prove we exist.

(Yes, I do suppose I exist as I accept the assumed axiom, but not because I can prove it to be true.)

[Edit:]On a side note: sometimes I'm amazed at the speech of some atheists who assert their opinions based on science as those which trump opinions based on faith. One is a stance built upon ultimately subjective evidence which itself has been built upon axioms - assumptions made that can never be proven but allow for all logic and reasoning. The other is a stance built upon ultimately subjective evidence - if you can call personal experience and posteriori justification evidence - which itself has been built upon assumptions made that can never be proven but allow for all illogical thought. We, as a whole, over simplify one of the most complex issues in all of conscious being. In the end, the only thing of value is epistemology which decisively humbles the most arrogant among us.
