DAVID’s comment: This seems to be a complex molecular machine structure, which may be so complex it can only be developed by design. It seems that these bacteria are brighter than H. habilis who couldn't invent a spear!

It seems you’re beginning to cotton on. The alternative to bright bacteria, of course, is that your God could not possibly have produced the human brain without first preprogramming bacteria to invent spears with which to stab amoebas.
