Nevertheless, the fact that I am writing produces stronger evidence of my existence that anyone could produce of my non-existence. In other words, your belief that I am here must be entrely based upon the fact that these words appear on your computer monitor. You acknowledge that I am here because you see my works, not because you see me.

If you want information on the evidence of God, feel free to contact me personally at firstname.lastname@example.org.

And if the scales are tipped to the left, would not a wise man say that the left side is heavier?
