Most of us have read and accepted the verdict of science - that we are the chance result of billions of years of evolution from single-celled creatures, to sea-born creatures, to reptiles, birds, mammals, to apes and finally to man. But the Vedas and Puranas have different theory of evolution which is now even accpeted by reputed scientists of NASA :
THEORY NO. 1: ALL STARTED FROM VISHNU
Vedas say that before the creation of the universe Lord Vishnu is sleeping in the ocean of all causes. His bed is a giant serpent with thousands of cobra like hoods. While Vishnu is asleep, a lotus sprouts of his navel (note that navel is symbolized as the root of creation). Inside this lotus, Brahma resides. Brahma represents the universe which we all live in, and it is this Brahma who creates life forms.
THEORY NO. 2 : IDEA OF MULTIVERSE
Vishnu is the personification of the eternal multiverse that exists forever without any beginning or end. Brahma is the personification of our temporary physical universe that was created in the big bang. Brahma is said to have been created from the navel (which is a single point) of Vishnu, described as a lotus blooming out of the navel, much like our big bang universe.
THEORY NO. 3 : UNIVERSE IS A TEMPORARY PLACE
Now this universe represented by Brahma is not a permanent universe, it is temporary, Brahma lives for 100 years, says the Vedas, and then dies and then a new universe (Brahma) is born. So as per Vedas, our universe lives for 100 years. Talking of time measurements - Brahma lives for hundred years say Vedas and we are in the first day of the 51st year of the Brahma.
THEORY NO. 4 : BIRTH AND REBIRTH OF BRAHMA
For now, Brahma represents our universe which has birth and death, a big bang and a big cruch, from a navel singularity. Vishnu represents the eternity that lies beyond our universe which has no birth or death and that which is eternal! Many such universes like ours exist in Vishnu. Vedas say that thousands of Brahmas have passed away! In other words, this is not the first time universe has been created.
THEORY NO. 5 : THEORY OF COSMIC MAN – PURUSHA
In the Rig Veda (the first scripture of Hinduism, containing spiritual and scientific knowledge) it says that the universe was created out of the parts of the body of a single cosmic man Purusha when his body was sacrificed. There the four classes (varnas) of Indian society come from his body: the priest (Brahmin) from his mouth, the warrior (Kshatritya) from his arms, the peasant (Vaishya) from his thighs, and the servant (Shudra) from his legs.
THEORY NO. 6 : MODERN SCIENCE ACCEPTED VEDAS
Some scientists have suggested that, following the Big Bang, the process of the expansion of the universe will eventually be reversed and at some distant point in the future will start to contract, eventually imploding into a `Big Crunch’. This could lead to another ‘Big Bang’, with a new universe being formed. This somehow relates to the present Brahma years coming to an end.
THEORY NO. 7 : THEORY OF PRALAY
A universe endures for about 4,320,000,000 years (one day of Brahma, the creator or Kalpa) and is then destroyed by fire or water elements. At this point, Brahma rests for one night, just as long as the day. This process, named Pralaya, repeats for 100 Brahma years (311 Trillion, 40 Billion Human Years) that represents Brahma's lifespan. Brahma is regarded as a manifestation of Brahman as the creator.
THEORY NO. 8 : THEORY OF OM
The universe is often said to be born from the sacred syllable Om, or from an inert void in which "there was neither being nor non-being ...death nor non- death", a single principle from which emerged the diversity of life. From this void desire was born, and from desire came humans, gods and demons.
THEORY NO. 9 : THEORY OF GOLDEN EGG
In earlier Vedic thinking, the universe was created by Hiranyagarbha (here interpreted as 'the golden embryo') or by Prajapati who was born from the Hiranyagarbha (here interpreted as 'the golden womb'). Prajapati was later identified with the puranic Brahma. Other gods are credited with acts of creation, primarily the act of propping apart the sky and the Earth - gods who are said to have done this include Indra, Varuna and Vishnu.
THEORY NO. 10 : BRAHMA SURVIVAL ON BREATHE OF VISHNU
Each Garbhodakasayivishnu exhales and inhales and with each breath a Brahma is born who lives for 100 Brahma years and dies with the breath of Garbhodakasayi vishnu. Each Brahma creates a universe which comes to an end with partial annihilation after several Brahma years. And this cycle begins again.
