Unlike what most people believe, the movie Volcanoes of the Deep Sea shows that life could have stemmed not from the sun but from the earth's internal heat source: underwater volcanoes.
The first evidence that supports this is matching hexagonal fossils discovered in Spain and in the mid-ocean ridge in the Atlantic Ocean where underwater volcanoes can be found, displaying the possibility that life originated in this area.
Other types of life, like shrimp and coral, who live in the same environment show that it is possible to thrive in such harsh conditions.
It was only recently that scientists had the resources and technology to explore these previously inaccessible environments. Even after the development of this technology we have yet to find a living specimen responsible for these mysterious hexagonal shaped fossils that possibly hold the secret to the origin of life on earth.
