Question

determine the statements that describe early earth according to current scientific understanding. early earth may have had life originate from inorganic molecules that arrived by comets only. early earth may have had life originate from inorganic molecules that formed organic molecules, carbon based molecules. early earth may have had life originate from organic molecules that arrived by celestial objects such as comets, asteroids, and meteorites. early earth had volcanic activity spewing gases into the atmosphere but when oxygen gas was added is being studied by scientists analyzing early fossil rock formations. early earths surface was bombarded by celestial bodies

Explanation:

1. Life on early Earth may have originated from organic molecules brought by celestial objects like comets, asteroids, and meteorites, not just comets for inorganic - molecules. Also, inorganic molecules could have formed organic, carbon - based molecules through chemical reactions on early Earth. Volcanic activity was present on early Earth, and the addition of oxygen is a subject of study via fossil rock analysis. The surface of early Earth was indeed bombarded by celestial bodies.

Answer:

Early Earth may have had life originate from inorganic molecules that formed organic, carbon - based molecules.
Early Earth may have had life originate from organic molecules that arrived by celestial objects such as comets, asteroids, and meteorites.
Early Earth had volcanic activity spewing gases into the atmosphere but when oxygen gas was added is being studied by scientists analyzing early fossil rock formations.
Early Earth's surface was bombarded by celestial bodies.
