Question

The theory that explains that life came from extraterrestrial is
A. Panspermia
B. Abiogenesis
C. Spontaneous generation
D. Special creation

Answer 1

It is believed that the earth was formed 4.8 billion years ago.
After its formation, it was still so hot that no life could possibly thrive. So after it cooled down then life must have started to originate.

Complete answer: In 1865, Richter suggested a theory that states the protoplasm of simple organisms in the form of some simple organisms might have reached earth by accident from some other planets of our galaxy or the rest of the universe. This is the theory of Panspermia. To this date, we have no proof of the existence of extraterrestrial life in our galaxy or the rest of the universe.

So, the correct answer is “Option A ”.

Additional Information:
Abiogenesis or origin of life is the evolution of life from non-living matter, such as simple organic compounds.
Spontaneous generation states that different living organisms have arisen all of a sudden from non-living substances (like butterflies from cheese, worms from mud, and so on).
Special creation is the creation of life by some supreme creature (also known as God).
In Hindu mythology, it is believed that the whole world including life was created by God “Brahma”.

Note: Spontaneous generation can be thought of as a form of the mechanism by which a certain organism is born, so it is repeated many times but on the other hand, Abiogenesis can be thought of as a unique event, so it is not repeated many times.
