When I ask an atheist a question I usually get an angry, arrogant, diatribe because I am violating his/her first “assumption”. For example, not a perfect example, If I asked an atheist “what is in this bottle?” And let’s say it was water. The atheist may assume its vodka. He then would tell me it is clear, it is liquid, it is in a bottle, the culture of that time was known to put vodka in bottles, etc. He could then go into great detail using science to prove it was indeed liquid, or build a solid case that the culture of that day bottled their vodka and so on. If at any point I tested the contents of the bottle and said I think it is water, I am ridiculed as stupid and dishonest by the atheist. An honest atheist will have to admit dating methodologies, the theory of evolution, and the Big Bang Theory are built upon “significant” assumptions and that these assumptions have not been validated to this date. This should allow for continued questioning.
