Perhaps we could widen the discussion a bit in terms of science and cosmology. We know that shrishti happened. In science it is known as the big bang. However scientists are in two minds whether pralay will happen or not. It is quite possible that it will and science will call it the big crunch. Maybe this will eventually lead to the next big bang. However it is not clear to me why the next creation will follow exactly the same path involving creation of something called Planet Earth inhabited by some sundry life-forms one species of which calls itself human and thinks it is intelligent enough to understand creation.
