Did Mahabharata really happen or is it all fiction?

Did Mahabharata really happen or is it all fiction? I am not going to retort with a YES or NO. Let me present few proven facts and leave the rest to the readers. The occurrence of Solar eclipse on the 14th day of war: Investigations conducted purely on phenomena like comet sightings, meteor showers revealed that a pair of eclipses occurred during the course of war. Ancient people preferred full moon day for any important event. Latest research by scholars with computer software shows that a lunar eclipse took place on the first day of war. We all know that a lunar eclipse takes place on a full moon day. So there are high chances that war started on full moon day and that day, a lunar eclipse occurred. Dr B N Narhari Achar, Department of Physics, Memphis University, USA also supported the theory of war starting on a full moon day. A solar eclipse is said to have taken place 13 days later. As per Mahabharatha,on the 14 day of war, when the sun appeared to be set, Jayadratha poked out to show that he was victorious against Arjuna . Suddenly the sun reappeared and Arjuna shot down Jayadratha’s head with Pasupathastra weapon. It goes that Lord Krishna hid the sun with his Sudarshana Chakra. Actually Krishna tricked Jayadratha with the knowledge of solar eclipse happening on that day. Researchers are using this eclipse pair with 13 days time gap to find out the exact date of Mahabharatha war. After serious analysis of all the eclipses that happened in Kurukshetra, it is found that six eclipse pairs have the time gap of 13 days. Such events happened in 3129 BC, 2599 BC, 2056 BC, 1853 BC, 1708 BC and 1397 BC . There are others that have low obscurity for solar eclipse, or have dominant penumbral lunar eclipse content and hence ignored. Mahabharatha war could have happened in any of those years and it can be taken as a proof for Mahabharatha war. 2. The Sunken city of Dwaraka: Until recently, the very existence of the city of Dwaraka was a matter of legends. Marine archaeological explorations off Dwaraka coast have brought to light a large number of stone structures beneath the sea. They also found that these structures are randomly scattered over a vast area. The ruins have been proclaimed to be the remains of the legendary lost city of Dwaraka. 3. Connection with present day cities: Most of the places mentioned in Mahabharatha are proved to be real ones. For instance, Hastinapura, the land of Kuru dynasty is now the state Uttar Pradesh; Indraprastha, the kingdom of Pandavas is now New Delhi; The Kingdom of Gandhar is now Afghansitan; Angadesh which was ruled by Karna is now Bihar. Based on the above facts, its upto you to decide whether the war happened or not
