I Know Poem by Freidoon Ranjbar

i know meaning of sunrise and sunset
i know meaning of philosophy and science
i know meaning of self-ralization and self-esteem
i know meaning of gene and metamorphosis
i know meaning of big bang and mountain range
i know meaning of real world and virtual world
i know meaning of universe and creation
i know meaning of love and empathy

But i don't know what is my mission on earth planet?
