:Dear dear Ansgar, 
 :There is no evidence whatsover that Zeno assumed anything. There is only historical records of what others said of him. The only facts relating to Zeno is what is currently observable, in existence now, and that is stuff written on paper or stone or whatever, which we may assume was written by someone, but we have no evidence of who wrote that material, other than other bits of paper or stone 'saying' who wrote what. 
 :You appear to lack even a modicum of understanding concerning the nature of 'facts'. 
 :As for the other, dear me, you lack the simplest of understanding. You may calculate whatever you want, but there is absolutely no evidence (or tight correlations) between what you are calculating and what you assume those calculations relate to, or are correlated with. Could be angels on pinheads, for all the evidence I've seen.
