Signs. That life on earth has existed for a very, very long time. While on tour last summer we visited my cousin in Antequera, Spain. He brought us to see the stunning limestone landscape at El Torcal de Antequera. El Torcal is over 150 million years old and is home to some fascinating records of marine life during the Jurassic period. The chubby little finger belongs to my cousin’s young son – a sign that human life is set to continue for at least one more generation.
