700 million years ago was near the end of this era. It is the longest era lasting almost 4 billion years! The Earth is very cold, but at least there is life. Around 1.7 billion years ago single-celled creatures started appearing, and 30 million years ago multi-celled creatures started to come! There are less volcanoes, but the ones that were there created huge mass of land. There are tons of plants that are releasing oxygen into the air. Ah sweet fresh air. -
