Leonardo da Vinci's geology work

Leonardo da Vinci found out that the earth has been here for a very long time before humans. He knew this because he found shells and other things from the ocean at high places which he thought meant that the sea level must have been up there in the past. So he thought it would take a very long time to make the sea level go so much lower than back then.
