The modern concept of the origin of life is based on the idea of biogenesis from pre-existing forms. This means that life arose from other living organisms. It is widely accepted that life on Earth originated through a process called abiogenesis, where non-living molecules eventually formed the first living cells. According to this concept, simple organic molecules in the early Earth`s environment combined to form more complex molecules like nucleo proteins. These molecules then aggregated into structures called coacervates, which were the precursors to the first cells.

While option 1 mentions the aggregation of molecules into coacervates, it is important to note that this was a step in the process of biogenesis, not the entire explanation of the origin of life.

Option 2, extra-terrestrial seeding, suggests that life on Earth originated from microorganisms or organic material from space. However, this hypothesis is not widely supported and lacks substantial evidence.

Option 3, spontaneous generation, is an outdated theory that suggests life can arise from inanimate matter. This concept has been disproven and is not considered the modern understanding of the origin of life.

In conclusion, while the process of abiogenesis and the formation of coacervates are important factors in the concept of the origin of life, the
