Lemon Tree
They think that everything evolved from chemicals, but where did the chemicals come from? That they do not know. Since the Supreme Personality of Godhead is the cause of all causes, He can produce immense quantities of chemicals to create a situation for chemical evolution. We actually see that chemicals are produced from living entities. For example, a lemon tree produces many tons of citric acid. The citric acid is not the cause of the tree; rather, the tree is the cause of the acid. Similarly, the Supreme Personality of Godhead is the cause of everything. He is the cause of the tree that produces the citric acid (bījaṁ māṁ sarva-bhūtānām (BG 7.10)). Devotees can see that the original potencies causing the cosmic manifestation are not in chemicals but in the Supreme Personality of Godhead, for He is the cause of the chemicals.

(SB 6.16.36 purport)
One day My mother, Śacī, offered food to Śālagrāma Viṣṇu. She offered rice cooked from śāli paddies, various kinds of vegetables, spinach, curry made of banana flowers, fried paṭola with nimba leaves, pieces of ginger with lemon, and also yogurt, milk, sugar candy and many other foods.
(CC Madhya 15.54-55)
The lemon tree is a living entity that produces many lemons, and within each lemon is a great deal of citric acid. Therefore, if even an insignificant living entity who is but a part of the Supreme Lord can produce so much of a chemical, how much potency there must be in the body of the Supreme Personality of Godhead.
(CC Madhya 16.81)
