Forget the masses, back then, even the thinking persons considered most elements of nature and the outer space as Gods because they never understood what was happening. Today the sensible man has no God to fall back on. Vast extents of outer space have been explored and there's theories to explain most of what is seen and even not seen so that we know its just a bunch of matter going around in meaningless precision. The elements of nature too have been reduced to equations. So much so that today's weather prediction systems are so accurate that one isn't sure whether those systems predict the weather or decide the weather. Just a few Gods of yesteryear are existent today, mostly supermen. And even they need scientific approval. Gone are the days when people just took for granted a christ or a krishna. Today, there are scientists carbon dating fossils and what not to check whether there really was a christ, or a krishna.
The Gods are dying. So why are you alive?
