Adam was the first person on earth and he was created by god
Unless you count God himself (Genesis 1:1- 'In the beginning, God created the heavens and the earth.... and the spirit of God was hovering over the waters.') the first thing on earth would be water... it was formless and empty, dark and there was no land.
