… Martian Life through Meteorites.
""Most work on meteorites and life is concerned with two areas of research," explained lead author Dr. Alastair Tait, of Monash University.
"Panspermia, the idea that life is carried inside debris blasted off a fertile planet by giant impacts, and travels through space to land on a dead planet, thus colonizing it."
"Or a pre-biotic pantry delivering all the right ingredients to kick start the origin of life."
"Our theory adds a third avenue of research, which is the interaction between astro-materials and an existing biosphere," he added…"

"We solved the problem of abiogenesis, it's all meteorites carrying life across the universe. Case closed !"
"And where does the life on the meteorites come from ?"

Patrick, I think you are having difficulty with your definitions. The possibility that pre-existing life was brought to Earth by meteorites is not an example of abiogenesis, rather Panspermia. The possibility of precursors chemicals needed for life were brought to Earth by meteorites so life can form here is an example of abiogenesis. It is an important distinction that the authors make, that you may have missed.
See the panspermia portion of the quote Armand provides.
