At the outset the author tells that God may not come down from the heavens to convince us whether He exists or not. So we have to find out the truth about Him ourselves only.
Next, he focuses our attention on the fact that a time has arrived when we should think afresh about the existence of God based on the present level of our intellect since the intellect of the people who had originally evolved the concepts of God was very poor for many understandable reasons as compared to the present level of our intellect which seems to have reached almost a pinnacle.
He hints at their extremely low intellect by pointing at the following aspects.
(i) Galileo Galilei had to bear extreme humiliation during his life just to have made them aware that earth revolves around the sun not the sun around the earth as they used to believe and it had taken them as long as 359 years to have changed their misconception.
(ii) They had a notion that the sun and the moon disappear during solar and lunar eclipses because some demon must be devouring them while today even a school-going child knows that the sun and the moon disappear only when either the moon hides the view of sun or the shadow of earth falls on the moon.
(iii) They had a notion that earth must be shaking during the earth quakes when the God may be getting angry with them not because of slippage of the lower layers of earth under the upper layers of earth as is well known to all of us.
The author tries to tell in a scientific a manner if God should have created the Universe why He should have been neither “animate” nor “inanimate” at the time when He may have created the Universe.
He has stressed that we should believe in the existence of God mainly because every system such as the recycling of water bears a stamp of so high a level of intelligence that no human beings could be perceived to have had when such systems should have been evolved instead of any other reason and should pay Him regard for having made us so intelligent as we are and so capable of exercising our own discretion as we are able to exercise more than for any other reasons since whatever we are today, we are because of our intelligence and our power of exercising own discretions only more than anything else.
However he opens up a debate if God did not evolve any system to check loss of solar energy by putting the sun rays, amounting to almost as much as 99.9 % of the rays emitted by the suns, that do not get intercepted by the planets, the asteroids or the satellites of the planets but escape farther deep into space to get frozen, to some use it grosses up to a colossal loss of solar energy which does not only reflect very badly on His part, it shames us also for having believed that He is Supreme, to whom we may never be able to attribute any lapse ever.
