I believe everything happens in a series of events,
each step taken will eventually affects either our lives and body or maybe others,
when we couldn’t find out the missing step,
we would tend to claim the event as a coincidence,
there’s nothing without a color of reason,
everything will have something causing it,
things may be unpredictable,
but it happens after a series of events,
not a coincidence.
Coincidence is not a part of science,
things need to be proved,
but the question is,
what exactly is science, which you fully depend on it to approve something?
science is a good thing,
but to depend on it alone is a weakness.
