When your logic ends in a paradox it is a good sign that you have missed some vital clue or have misunderstood something fundamentally important in what you are reasoning about.
For example, people assume that time is a strict progression of cause to affect, but actually, from a non-linier, non subjective point of view it is more like a big ball of wibbily wobbly timey wimey...stuff spacetime is expanding and the speed of light is constant therefore the general theory of relativity needs to be taken into account.
