The earth has never been alive. It has been in existence in its present form for about 5 billion years. Some creatures inhabiting it have and are alive.
The chambered nautilus has existed virtually unchanged for 500 million years.
Rats have been alive for hundreds of years. Rats have been alive for around for at least 900 years on Earth.
Antarctica is 10% of the earth's surface, so at least that long.
The nautilus is an ancient symbol of the spiral of our lives. As long as we have had stick and charcoal, we have been trying to reproduce the many, and ever growing, chambers of this illusive denizen of the deep. As the nautilus grows it continually builds new chambers to its shell and closes off the previous chambers. This represents that although we take who were with us through life, we can never go back. Further, as body art this animal shows that you have grown, and will continue to grow as long as you are alive.
A nautilus can grow to about 8 inches (20 cm) long.
