What is early earth atmosphere like?

This is quite a controversial topic. After an experiment, scientists believe that the early earth had an atmosphere that contained amino acids, which gave a purplish-pink tinge to the atmosphere and helped life grow. What is most widely accepted is that the early earth was a fiery hot ball made of molten magma.

As meteors hit its surface, the lighter metals floated up and the heavier elements sunk down. This created the first land. Volcanoes that were erupting CO2 created ideal conditions for plant life, that absorbed only CO2, to thrive. Comets that crashed down released water, letting plants absorb its minerals and grow ever more healthily. Life began to grow this way. The land began to cool down.

The plants grew to large numbers, and began to release more oxygen than the amount of CO2 they could take in. Gradually, these plants began to die out. However, with the amount of oxygen they released, the plants lay a foundation for life.
