Yes, they were made, however the televised argument to debunk that is that the Earth was in a state that life should not have been able to form in the first place. 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.
I'm not saying it is logically sound, but it is a strong possibility. We just don't know. My theory is just as viable as any other about how humanity came to be. Short of a time machine, we will never truly know. That is just my theory.
