This thread is actually indicative of a big problem in the kiruv world (both rechokim and kerovim). “If you don’t believe my answer, its because you are clinging to tiny improbably chance that it may not be true.”
This thread also shows that people don’t really understand the difference between correlation and causation. Never mind that revisionism is high up on many people’s lists nowadays.
However, one atheist (a non-Jewish woman, former Christian, who is very knowledgable and thought deeply before abandoning her faith) asked me this question which I couldn’t answer effectively “You expect me to believe that G-d created matter because otherwise where would matter come from. But if you can believe that G-d always was, is and always will be, why can’t I assume the same for matter?”
