When you think about it, human existence is utterly futile.
Quote (from a futile website):
Most humans do not think about these things, because it leads them to be depressed. They would rather go on living in their elaborate delusions that they're life actually means something, then face the crippling reality that everything, and I mean everything, you do is utterly pointless. You will die. You will be forgotten. In a hundred, or even a thousand years of time, there will likely not even be a trace that you ever existed.
Furthermore, there is no God. "God" is a copout people use because they don't want to face the inherent futility of the human existential condition. They reason that even if they can't find the reason behind existence, there is some mystical being that truly knows the reason, and that can endow the universe with some supernaturally ascribed purpose. This is pure delusion. There is no evidence of any supernatural purpose. People cling to this because they simply do not want to face the harsh reality of the inherent futility and absurdity of the human condition.
So, in conclusion, there is no meaning to existence, everything you do is a mere exercise in futility, life is utterly pointless, there is no God, and in a thousand years time you will be completely forgotten and all of your attempts to achieve anything will be erased. Have a nice day.
