Do you honestly think that's intelligent, I point out it's egotistical to believe we "need" to live (when record level of species are going extinct as we speak, even) and you tell me to go kill myself?

Also, where did you get the idea that I "believe in nothingness"? If you mean nihilism, nihilism is stupid.

Believing in "the unimportantness of the human existence" is right for a very simple reason: "Importance" is a myth. We are no more "important" than the T-Rex or the dodo or some genesplicing-technologically created animal in the future.

EDIT: Also, living a happy life is irrelevant to the conversation in general and specifically it's irrelevant to "finding a point in it", you're confusing the myth of "purpose' with sense of contentment or sense of accomplishment etc.
