Hint: Oparin and Halden mainly told about the chemical evolution, and it states that life on the earth is originated from the non-living things or abiogenetic organisms, where Miller observed the formation of amino acids from hydrogen ions water at the temperature of 800-degree centigrade.
Complete answer:
This Oparin and Halden hypothesis came up in the year 1924.
Where Oparin hypothesized that organic molecules might have formed from very simple none living molecules or inorganic molecules.
He also states that those molecules may form the colloid aggregates, or coacervates, in an aquatic or in the moist environment
These coacervates which are formed from that organic molecule have the capability to absorb.
And at the same time those organic compounds which are formed from the environment in a way reminiscent of metabolism.
So those organic molecules could have taken part in evolutionary processes, finally led to the first lifeforms.
Similarly in the year 1929, Halden read about the Oparin hypothesis and he also hypothesized that on the earth from the reduction reactions, more complex organic molecules are formed from the simple molecules and he considers the ocean as a huge cooking pot and there is sunlight so that so many reactions might happen.
So when the meteorites were analyzed they observed the similar compounds there also, so from this it was confirmed and concluded that a similar process was taking place somewhere in the space.
Note: A meteorite is a small piece of debris, which may form the asteroids and comets, at the same time, 8% of the meteorites were made up of achondrites, it was originated in the outer space and it survives the passage through the atmosphere, to reach the surface of planet or moon.
