When you look all the stars and planets around Earth, you will see rocks, maybe water, all kinds of chemical elements etc. But none of them has that magic dust that creates life. So, the main question is: Where that magic dust came from to Earth? Was it travel on some asteroid that hit Earth many bilions years ago?  To answer the question whether there is life or not, we must first understand how life was form on the Earth and where it has come from. It is very much possible that super intelligent species spread certain dna material all across universe to ensure magic dust existence and survival. I am almost sure in one thing, that magic dust didnt form on Earth! It came to our planet from somewhere!,(reply>), @xjohnny1000 How you explain then, that we couldnt create life in lab from scratch.  We have liquid water, all kinds of chemicals etc. and yet, there is no way to create life using elements that we see in nature. How is that possible?
