Other Theories

Scientists' idea of the primitive earth

Some have suggested the origin of life is a mix of these ideas, while others believe an entirely different idea, and there are those who think new natural laws are needed.

Directed Panspermia is the idea that other alien forms within the universe brought life to earth in a spaceship. This is very unlikely.

Another idea is that other life forms within the universe created life. This is also very unlikely.

Yet another possibility is that new natural laws are needed. Maybe there are laws that science has not discovered yet. People speculate that life may be using some unknown law.

All these are theories, and there are many more out there. It is up to the reader as to which one he/she believes.
