Another point in this verse is that fathers and mothers have protective feelings for their children even in bird and beast society, not to speak of human society. Kali-yuga, however, is so degraded that a father and mother even kill their children in the womb on the plea of their scientific knowledge that within the womb the child has no life. Prestigious medical practitioners give this opinion, and therefore the father and mother of this day kill their children within the womb. How degraded human society has become! Their scientific knowledge is so advanced that they think that within the egg and the embryo there is no life. Now these so-called scientists are receiving Nobel Prizes for advancing the theory of chemical evolution. But if chemical combinations are the source of life, why dont the scientists manufacture something like an egg through chemistry and put it in an incubator so that a chicken will come out? What is their answer? With their scientific knowledge they are unable to create even an egg. Such scientists are described in Bhagavad-gita as mayayapahrta jnanah, fools whose real knowledge has been taken away. They are not men of knowledge, but they pose as scientists and philosophers, although their so-called theoretical knowledge cannot produce practical results.
