First of all, mahabharat and ramayana are ithihas, not myths…
Now let’s go through some of the evidences which I’ve gathered from various sources!!
1. Records of Bharat dynasties and real historical lineage
It is mentioned in Aadiparva, the book of the beginning. Which is the first of eighteen books of the Mahabharata, chapter 62 about the records of the Bharat-Dynasty (interestingly the name of India ‘Bharat’ has the origin from it), and its lineage are recorded .More than 50 kings and their dynasties starting from king Manu have been presented in detail. A fictional tale as we know would hardly use 5-6 of them.
2. It is written as Itihas (History)
In Mahabharata it is clearly written that it is a “Itihas’ (Sanskrit word for History). The words “Puraan” and “Itihas” were specifically coined by the ancient people to categorize the “ancient” and “recent” events. Both the words denote history that has occurred at different times. If the intention of the writer was to write a poem or a work of fiction, he would have stated it to be a “Mahakavya” (epic) or “Katha” (story) which was a tradition at that time.
3. Description of modern world in ancient times
Read the description of Kaliyuga as mentioned in Mahabharata. Whatever Krishna predicted about future civilization in Kalyug (Modern Times) came true, but please note that these were not prophecies but are the part of Geeta. And remember – this was written thousands of years ago! Fiction? Unlikely because there are way too many corroborations and tallying circumstances for it to be fiction.
4. Archaeological evidence of the lost city of Dwarka
Marine archaeology while exploring the ancient submerged city of Dwaraka in Gujarat, uncovered further evidences in support of statements in the Vedic scriptures. An entire submerged city at Dwaraka, the ancient port city of Lord Krishna with its massive fort walls, piers, warfs and jetty has been found in the ocean as described in the Mahabharata and other Vedic literature.
5. Real places mentioned in Mahabharata and archaeological evidence
More than thirty-five sites in North India have yielded archaeological evidence and have been identified as ancient cities described in the Mahabharata. Copper utensils, iron, seals, gold & silver ornaments, terracotta discs and painted grey ware pottery have all been found in these sites. Scientific dating of these artifacts corresponds to the non-Aryan-invasion model of Indian antiquity.
All places mentioned in Mahabharata are real places, all are identified and still exist with the same name. For instance, Hastinapur is in UP with multiple evidence of Mahabharata in Hastinapur. Indraprastha is the present day Delhi. Dwarka is located in Gujarat coast. Kurukshetra where the war actually happened is in present day Haryana very near to Delhi.
Interestingly this is not limited to only India. The Kekaya kingdom is located in today’s Pakistan, Madra Kingdom is located in today’s Pakistan. Gandhara Kingdom is located in today’s Afghanistan. Kambojas Kingdom is located in today’s Iran. Parama Kamboja Kingdom is located in today’s Tajikistan.
Recently researchers have found the city of Dwarka under the sea in the said place. Mahabharata cities are not limited to present day India because Mahabharata referred Indian subcontinent as Bharat.
6. Progression from Ramayana
Mahabharata is a continuation of the dynasties from Ramayana and it has a well established coherence in the chain of events. Even the relations between different kings and their dynasties in both the great “epics” match with each other.
If both were mere “epics” written by two entirely different persons, at two different point in times, why would everything match to even minute details? Mahabharata occurs thousand of years after Ramayana. What is the need for the author of the Mahabharata borrow the same ideas and characters as those of the author of Ramayana?
7. Astronomical references
The Udyoga Parva of Mahabharata narrates that, just before the War, Lord Krishna went to Hastinapur in the month of Kartika on the day when moon was at the asterism Revati.
On His way to Hastinapur, Krishna took rest for a day at a place called Brikasthala, and on that day the moon was at the asterism Bharani. The day on which Duryodhana turned down all the efforts of Krishna and made the war inevitable, the moon was resting at the asterism Pushya.
8. Myth of Aryan invasion theory
European scholars brought the nomadic Aryan tribes, into India after 1500 BC. How could these Aryans create Sanskrit language, gain so much knowledge and write all these texts before 700 BC? Great Indian thinkers including Lokmanya Tilak, Sri Arbindo, and Dyanand Sarasvati rejected the European theory.
9. Historical references that are true
Maurya, Gupta and Indo-Greek dynasties, are also recorded in our Purana. These dynasties are accepted only because they are also recorded by Greek historians. What about the dynasties that existed before the Greek historians?
10. Famous Oppenheimer quote
The architect of modern atomic bomb who was in charge of the Manhattan project was asked by a student after the Manhattan explosion, “How do you feel after having exploded the first atomic bomb on earth”. Oppenheimer’s reply for the question was, “not first atomic bomb, but first atomic bomb in modern times”. He strongly believed that nukes were used in ancient India.
As he witnessed the first detonation of a nuclear weapon on July 16, 1945, a piece of Hindu scripture ran through the mind of Robert Oppenheimer: “Now I am become Death, the destroyer of worlds”. It is, perhaps, the most well-known line from the Bhagavad-Gita, but also the most misunderstood.
11. Flying vehicles and nuclear war
The Indian Epics, especially the MAHABHARATA, pick up the thread of the tale of devastation and destruction. Sanskrit scholars could not understand what was being described in the Epics until the dropping of the first atomic bombs on Japan happened. The effects of radiation poisoning also became clear.
Now these details have been provided with details in Mahabharata. A details provided in Mahabharata can be roughly translated in English below:
Flying a swift and powerful Vimana (Aircraft) hurled a single projectile Charged with all the power of the Universe. An incandescent column of smoke and flame as bright as ten thousand Suns rose ….it was an unknown weapon, an iron thunderbolt, a gigantic messenger of death, Which reduced to ashes.
The Entire race of the Vrishnis and thr Andhakas….the corpses were so burned as to be unrecognizable. Their hair and nails fell out, pottery broke without apparent cause and the birds turned white. After a few hours all foodstuffs were infected. To escape from this fire, the soldiers threw themselves in streams to wash themselves and their equipment.
12. Real places with evidences that correlates with Mahabharata
One of the good examples is a place, a few kilometers from Gwalior, Morena (M.P.), India, where mother of Pandavas the heroes of Mahabharata, Kunti invoked the Mantra given by Maharishi Durvasa and summoned Surya Bhagwan (Sun God) who appeared on a seven horsed chariot.
The dazzling heat of the chariot and the horses melted the rock, leaving imprints on the rock. A picture showing the same.
13. The enormity of details provided
Mahabharata has enormous details more than what ancient people can manage
The Mahabharata is the longest known epic poem and has been described as “the longest poem ever written”. Its longest version consists of over 100,000 shloka or over 200,000 individual verse lines(each shloka is a couplet), and long prose passages. About 1.8 million words in total, the Mahabharata is roughly ten times the length of the Iliad and the Odyssey combined.
In today’s world of smartphone and computers it may seem easy to maintain coherence with a large amount of data. Consider this in ancient times, where there was no Ctrl+F to search through the enormous documents, maintain consistency and infer stories and cite references.
14. Physics in Mahabharata
Whether it is time travel, quantum mechanics or gravity all find some mention in Mahabharata!
Reference of time Continuum in mahabharata. The story follows a king, his daughter, and their search for a perfect suitor.
Revati was the only daughter of King Kakudmi, a powerful monarch who ruled Kusasthali, a prosperous and advanced kingdom under the sea. Thinking no one could prove to be good enough to marry his beautiful daughter, Kakudmi took Revati with him to Brahmaloka, the home of Brahma, to ask the god’s advice about finding a suitable husband for her.
Brahma was listening to a musical performance when they arrived, and so they waited patiently until the performance was finished. Finally, King Kakudmi humbly bowed and made his request:
“O Brahmâ! To whom shall I betroth this daughter? I have come to you to ask on this point I have searched for many princes and seen also a good many of them and none of them is to my liking and so my mind is not at rest.”
Brahma laughed at the foolishness of the King.
“O King! The princes that you thought would become the bridegroom of your daughter, all died; their sons and grandsons and their friends even have all passed away.”
Time, as God Brahma goes on to explain, runs differently on different planes of existence. During the time they had waited in Brahmaloka to see him, 27 chatur-yugas, had passed on Earth.
Everything that Kakudmi had and owned, his friends and family, his sons and wife, his armies and treasures, had vanished with the time that had passed.
The King and his daughter were overcome with astonishment and grief for everything they had lost, but Brahma comforted them, and recommended a worthy husband currently on earth: Balarama, the twin brother of Krishna.
There are many claims of radioactivity like in Jodhpur which is at least 710 Km distant from the war of Kurukshetra. Radioactivity has been quoted as one of the scientific argument presenting evidence at different places in India including giant unexplained crater near Bombay.
