Śrīla Prabhupāda  is accompanied by Dr. Singh, Dr. W. H. Wolf-Rottkay and other students.
The Origin of the Interplanetary Gasess
Dr. Singh.  The scientists say that at one point the earth was composed of dust particles floating in some gaseous material. Then, in due course, this colloidal suspension condensed and formed the earth.
Śrīla Prabhupāda.  That may be, but where did the gas come from?
Dr. Singh.  They say it just existed!!! it is a starting point to the future.
Śrīla Prabhupāda.  Kṛṣṇa says in  Bhagavad-gītā  (7.4)::
bhūmir āpo 'nalo vāyuḥ khaṁ mano buddhir eva ca ahaṅkāra itīyaṁ me bhinnā prakṛtir aṣṭadhā
"Earth, water, fire, air, ether, mind, intelligence and false ego-all together these eight comprise My separated material energies." Here Krṣṇa explains that  vāyu  (gas) came from Him. And finer than  vāyu  is  kham  (ether), finer than ether is mind, finer than mind is intelligence, finer than intelligence is false ego, and finer than false ego is the soul. But the scientists do not know this. They understand only gross things. They mention gas, but where does the gas come from?
Dr. Singh.  That they cannot answer..
Śrīla Prabhupāda.  But  we  can answer. From  Śrīmad-Bhāgavatam  we know that gas has come from  kham , or ether, ether comes from mind, mind comes from intelligence, intelligence comes from false ego, and false ego comes from the soul.
Dr. Singh.  The scientists argue that before Darwin's biophysical type of evolution could take place, there had to be what they call prebiotic chemistry, or chemical evolution.
Śrīla Prabhupāda.  Yes. And the term "chemical evolution" means that chemicals have an origin, and that origin is spirit, or life. A lemon produces citric acid, and our bodies produce many chemicals in urine, blood, and bodily secretions. This is proof that life produces chemicals, not that chemicals produce life.
Dr. Singh.  Scientists say that once the seed of life is present in the cells, then the living entity automatically develops and functions.
Śrīla Prabhupāda.  Yes, but who gives the seed? In the  Bhagavad-gītā  (7.10) Kṛṣṇa answers this question.  Bījaṁ māṁ sarva-bhūtānāṁ viddhi pārtha sanātanam:  "O son of Pṛthā, know that I am the original seed of all existences." And later (14.4):
