The Third Canto of Shrimad Bhagavatam, where Lord Kapila (An incarnation of Krishna who appeared in Satya-yuga as the son of Devahuti and Kardama Muni) instructs His mother at least two million years ago.
Sage Kapila is the founder of Samkhya Pkilosophy.
Interstingly Samkhya does not believe in God.
He cursed and burnt to ashes the children of Sakara,after whom the Oceans get the name, Sagara, for disturbing His Meditation.
The descendant ,Bhagiratha brought the Ganges from Heavens , midst great difficulties to alleviate their suffering and have them granted Moksha.

“Under the supervision of the Supreme Lord and according to the result of his work, the living entity, the soul, is made to enter into the womb of a woman through the particle of male semen to assume a particular type of body
. On the first night, the sperm and ovum mix, and on the fifth night the mixture ferments into a bubble. On the tenth night it develops into a form like a plum, and after that, it gradually turns into a lump of flesh or an egg, as the case may be.
“In the course of a month, a head is formed, and at the end of two months the hands, feet and other limbs take shape. By the end of three months, the nails, fingers, toes, body hair, bones and skin appear, as do the organ of generation and the other apertures in the body, namely the eyes, nostrils, ears, mouth and anus.
“Within four months from the date of conception, the seven essential ingredients of the body, namely chyle, blood, flesh, fat, bone, marrow and semen, come into existence. At the end of five months, hunger and thirst make themselves felt, and at the end of six months, the fetus, enclosed by the amnion, begins to move on the right side of the abdomen. Deriving its nutrition from the food and drink taken by the mother, the fetus grows and remains in that abominable residence of stools and urine, which is the breeding place of all kinds of worms.”
The Fetus in The Womb.
“Placed within the amnion and covered outside by the intestines, the child remains lying on one side of the abdomen, his head turned towards his belly and his back and neck arched like a bow.
The child thus remains just like a bird in a cage, without freedom of movement. At that time, if the child is fortunate, he can remember all the troubles of his past one hundred births, and he grieves wretchedly. What is the possibility of peace of mind in that condition?
“Thus endowed with the development of consciousness from the seventh month after his conception, the child is tossed downward by the airs that press the embryo during the weeks preceding delivery. Like the worms born of the same filthy abdominal cavity, he cannot remain in one place. The living entity in this frightful condition of life, bound by seven layers of material ingredients, prays with folded hands, appealing to the Lord, who has put him in that condition.
“The ten-month-old living entity has these desires even while in the womb. But while he thus extols the Lord, the wind that helps parturition propels him forth with his face turned downward so that he may be born. Pushed downward all of a sudden by the wind, the child comes out with great trouble, head downward, breathless and deprived of memory due to severe agony.
“The child thus falls on the ground, smeared with stool and blood, and plays just like a worm germinated from the stool. He loses his superior knowledge and cries under the spell of maya (“illusion” which deludes the living entity into forgetfulness of the Supreme Lord). Under illusion a man thinks he can be happy in this temporary material world. After coming out of the abdomen, the child is given to the care of persons who are unable to understand what he wants, and thus he is nursed by such persons. Unable to refuse whatever is given to him, he falls into undesirable circumstances.

Very informative article Sir. Mostly, people from other religions claim that their texts are error free. But, Sanathana dharma is highly technical and different. For people who want to look at it as a way of life, it offers it in that manner.
However, for those who want to understand the world and human body and connect with it like a religion, it offers itself in that manner. Srimad Bhagavadam being such a rich text with series of revelations and most importantly, it is error free and it covers a wide range of facts.
