The entire planet is coated with bacteria and bacteriaphages. It's entirely possible that any new life created through abiogenesis is almost immediately outcompeted by evolved microbes.
- tsimionescu 6y agoIn today's world, perhaps, but it must have taken vast amounts of time until the first bacteria covered the planet. If abiogenesis were a frequent event on the early earth, there should have been plenty of space for more than one lifeform to survive before life became ubiquitous. And of course it's possible, but it shouldn't be the default assumption either.
