So, continuity doesn't exist because infinity doesn't exist either, and the assumption of existence of continuity was a total brain fart, but an artificial deliberate continuity was adopted by fabricating those (EpsilonDelta) Distances just for practical needs which aren't truly any mathematics for sure
