<span>The Earth was
formed 4.6 billion years ago from mixes of hot gases and solids. During those
days Earth almost had no atmosphere and its surface was molten. Through time
the Earth cooled and the atmosphere formed consisting mainly of gases that
spewed from volcanoes. The atmosphere was extremely hot, composed of hydrogen,
sulfide, methane, and carbon dioxide that is 200 times more potent compared to
today’s atmosphere. Half a billion years later, Earth started to cool and
solidify its surface making it conducive for water collection and making life officially
inhabit the planet.</span>
