The atmosphere was too toxic, and the places that would have been perfect grounds for such formation of life was too remote for an electrical charge to set it off. I don't remember what show it was on, but they did a lot of tests on that and couldn't make primordial soup using proposed environments existing on Earth at that time.
Toxic? Most of the oxygen in the atmosphere was put there by life. Oxygen was originally a waste product. Water and the 'building block' elements and molecules were all present in the early Earth.
