I took this picture for two reasons:
first, I liked the huge rocks that look like some enormous gates (of nature) and
second, to show how small and insignificant humans seem next to them. Despite all of mankind's technological advances and the ability to influence and change nature, our evolutionary existence is just a very brief moment in the geological history of Earth. These rocks are probably millions of years old, being once at the bottom of an ancient sea.
The picture was taken in Ha Long Bay, Vietnam. Thank you for your comments.
