Atheistic men think that the cosmic manifestation has come about by chance, by a combination of matter, without reference to God. Materialistic so-called chemists and atheistic philosophers always try to avoid even the name of God in relation to the cosmic manifestation. For them Gods creation is impossible to understand because they are too materialistic. The Supreme Personality of Godhead is paramahamsa, or the supreme pure, whereas those who are sinful, being very much attached to material sense enjoyment and therefore engaging in material activities like asses, are the lowest of men. All their so-called scientific knowledge is null and void because of their atheistic temperament. Thus they cannot understand the Supreme Personality of Godhead.
