There must be someone some architect or someone else call it however you want, someone who created all this. Created us humans, created every single living creature on Earth. You can't really think it is created based on some luck. 
Your logic is flawed. You believe a simple thing like a cell cannot just come into being, yet you believe a creator did?
It wasn't the Creator Who came into existence. The Creator always existed. It was mankind that suddenly came into existence. And it looked to man like it was God Who came into existence, because when man came into existence, that was the first time he saw God... God Who had always existed.
