Answer:

Earth's first atmosphere 4.6 billion years ago was most likely comprised of hydrogen and helium (two most abundant gases found in the universe!)

-water vapor (produced rain - rivers, lakes, oceans)

-carbon dioxide

-nitrogen

As outgassing occurred over a period of millions of years, the atmosphere evolved to its current state
