I think what makes us different all the animals and why we are here todays is because we believe. We believed we are more powerful than other creatures on Earth, we believed we have someone with superpower up there, some of us believe in not believing this belief, we believe that we need to have principles and values in life either our own or those from our religion, we believe in many other such beliefs that were made by us. Can we ever give up living based on our beliefs and live by the truth?
You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe. - Carl Sagan
