I believe humans now have the knowledge available to understand how we came to exist.  The remaining question of why, is what drives the need for some sort of explanation.

Does it serve us well to manufacture conclusions without evidence?  We've been doing it for centuries, and it seems to placate our need for answers, or meaning, but I think it's a huge waste of time and energy that only creates more questions and frustration.

I believe in our ability to evolve beyond the primitive mindsets.  Our future depends upon realistic and rational thinking, not belief in man-made religious concepts as "knowledge".
