The entire course of cosmic history has been leading up to the creation and expansion of E. coli.  As you can see from the plot below, all salient events in E. coli history line up in a smooth exponential line.  This proves that Evolution favors the creation of E. coli since there is no other explanation as to why this plot would be exponential.  Hmmm?

Furthermore, since this trend has continued for 14.7 billion years, we can safely assume that E. coli will continue to expand eventually consuming the entire Universe.  This is because all trends always continue forever.  

This is all quite inevitable.
