I'm trying to start the church of the prime bacteria. I'm all for worshiping bacteria, it has a number of advantages over God:
1) We know it exists
2) Not only do we know it exists, but it's literally everywhere around and inside us. There are estimated to be ten times as many bacteria in the human body than human cells.
3) Bacteria could be the Progenitor, or Most Recent Common Ancestor, for all life on Earth today.
4) Bacteria, through photosynthesis and other metabolic processes, are largely responsible in a literal sense for the world as humans see it. Oxygen in the atmosphere, the nutrient cycle, etc. etc...
