Fear of the Unknown
"What is the meaning of our existence?"
"What is the purpose of life?"
To be honest, I'm tired of these questions. As far as I'm concerned, we'll never be able to answer them definitively in my lifetime, or quite possible in any lifetime. And not having the answer does not bother me one bit. In fact, I rarely ever think about it. And I doubt most people spend a lot of time really thinking about it either.
And yet so many people seem to need to cling to one of the various mythologies floating about to give them a sense of meaningfullness about their existence. "If there is no God, then what is the meaning of life?" is a common question asked on atheist blogs. While no other life form on this planet seems to need an ultimate purpose, we humans are just arrogant enough to assume that it was all created just for us.
I know you're not supposed to answer a question with another question, but since I don't know the answer anyway, what else have I got?
What if the only answer to these questions is "We don't know"? Would life suddenly become meaningless? Would you struggle to get out of bed every morning? Would your personal relationships fall apart? Would food lose all taste? Would what was once exciting and fun become boring and uneventful? Would you find the nearest gun and put an end to it all?
If so, I think that says a lot more about you than it does about our existence.
