I did not come up with my beliefs on my own. My beliefs come from the spiritual masters and advanced souls that I have come to respect from my fair consideration as being YES, better than the common man's understanding. I do not hold every ones views to be of equal quality.Atheists do not deny there is a reason for existence. They just don't define an answer that cannot be supported outside of assumptions and speculation which Theists tend to do.
Your assumptions and speculations are no better than the next man.
Similarly, I studied chemistry in school but I did not come up with science's chemical knowledge on my own. I respect the masters of chemistry that came before me.
