Interesting link and video. Abiogenesis according to Darwinism tells us that at one time the Earth’s atmosphere contained nitrogen, carbon dioxide, methane, etc but no oxygen. Lightning arcs through the gases generated amino acids and other pre-life requistes. These precursors of life were washed out of the atmosphere by rain and many these were collected into warm ponds. Some laboratory experiments have simulated these conditions so it has been shown how these complex molecules can be generated in the way described above (to a degree).
These chemicals combined in complex ways by accident until first self-replicating molecules and primitive single celled organisms appeared. Accidental mutations eventually led to algea and photosynthesis to absorb the carbon dioxide and excreted oxygen as a waste product. Survival of the fittest, utilizing the ‘waste’ product known as oxygen, took over from there.
It does seem that regardless of the possibility that exogenesis may have occured that we are still left with the same questions about how the first self-replicating molecules and single celled organisms formed in spite of whether or not this process originated on earth. I can’t answer your question to be honest with you on whether life originated on Earth or not.
