All worldviews have equal burden of proof. The frequent claim of atheists that Christian theism asserts something positive, i.e. the Triune God, while atheism (contrary to that) does not assert anything positive and has no burden of proof is false. Atheism positively asserts an incoherent plurality of unrelated brute facts which cannot account for themselves or for any fact of human experience whatsoever, be it knowledge, truth, morality, individual rational freedom, immaterial objects, etc. The list goes on and on.
The atheist, by his own contradictory presuppositions, is reduced to the absurdity of absolute skepticism -- all along challenging the Christian to account for knowledge based on the atheist's skepticism.1 The God of Christian theism does account for knowledge. That answer is intelligible and the atheist can understand that answer. The only objection the atheist has is he does not like that answer.
Contrary to the atheist we are not all on an epistemological Titanic. Only the atheist is on that ship.
1 By assuming everyone must be in the same epistemological situation the atheist has ascribed to the fallacy of pretended neutrality. That assumption is question begging. ↩
