The alleged signs are subjective. There is no measurable evidence for the existence of God, only philosophical reasoning that may be subjugated to bias, culture, or emotion. My friend, I think you are claiming that because you are suggesting that "arrogance" and "ignorance" is the reason atheists do not see the signs. To me, it sounds like you think all atheists are too arrogant to see things in your perspective as a muslim. If i'm correct, then I think this is absolutely fallacious. Some people are atheists for reasons besides these two and some do have intentions to seek truth. If i'm wrong, then please correct me.
