Jijith Nadumuri Ravi's website about the Hindu scriptures is a remarkable achievement and henceforth a very useful resource for scholars and for practising Hindus.

A cross reference from Valmiki Ramayana on location of Bhogavathi
It was in the South in the Indian Ocean. Chapter 4-41 gives the overall picture.

36b, 37, 38a. tatra= there; vishaala rathyaa= with broad, roads; durdharSaa= unvanquishable - city; sarvataH parirakSitaa= everywhere, safeguarded; ghoraiH= deadly; tiiSkNa damSTraiH= with harrowing, fangs; mahaa viSaiH= having fatal, venom; pannagaiH rakSitaa= by [such] serpents, protected; sarpaaNaam aalayaH= for snakes, an abode of; bhogavatii naama purii= Bhogavati, named, city - is there; yasyaam= in which; sarpa raajaH= serpents, king; mahaa ghoraH= highly, hazardous one; vaasukiH vasati = Vasuki, will be dwelling.

"There is a city named Bhogavati which is an abode of the snakes. It has broad roads and safeguarded from everywhere, and thus it becomes an unvanquishable city. Deadly serpents with harrowing fangs and fatal venom will be protecting it, in which the highly hazardous king of serpents, namely Vasuki, will be dwelling. [4-41-36b, 37. 38a]

hope all together will do best .and will request to others to save every live from the under earth and bring back to earth every grand or micro soul good or bad.

please save
please save to every one good or bad

I am impressed by your careful and pragmatic evaluation of possible chronology of the various actors in Jaya. I tend to agree with you that a "Vyasa" could be a title of capability and there could be several generations that carried on the story. The need to assume two Bheeshmas troubles me. Accordingly, I modified the table you published with a couple of new assumptions:

1. Men completed their educations at 16 and were considered mature at 20
2. Women were considered mature at 16

The table below results from these assumptions and you can see that there may be no need to assume more than one Bheeshma to fit the chronology. According to the modified chart, Bheeshma dies at 118 (which was probably very old even back then) and other people die at quite ordinary ages like 75 or 80. To re-form the table, please copy the block below into Excel and it should reformat correctly.

NOTE:
From the statements made in Discrepancy 1, I am inclined to think that there are actually 2 ancestral Janamejaya. One is a Kuru and the other is a Puru. I am also inclined to think that the Kuru Janamejaya is spoken of in Discrepancy 2. It seems advisable to read that the ancestral Kuru Janamejaya is the FOREFATHER in the lineage that leads down to King Santanu, while Vasya is the direct biological father of Dhritarashtra, Pandu and Valhika.

I believe there was an error in translation: In 94, Riksha is the son of Ajamidha and Samvarana is the son of Riksha. In 95, Samvarana is the son of Ajamidha and Riksha is said to be the fourth wife.

Another point of possible confusion relates to Daksha. Santhi Parva, section 207 states that sometimes Daksha is called Kasyapa and Kasyapa, son of Marichi, is sometimes called Arishtanemi.

95: Daksha begat Aditi, and Aditi begat Vivaswat, and Vivaswat begat Manu, and Manu begat Ha and Ha begat Pururavas.

207: The ten Prachetasas had one son between them, viz, the Prajapati called by the name of Daksha. This last has two names in the world, viz, Daksha and Kasyapa. Marichi had one son called Kasyapa. This last also has two names. Some call him Arishtanemi, and some Kasyapa.

Discrepancy 1:
94: And it has been heard by us that Kuru's highly intelligent wife, Vahini, brought forth five sons, viz, Avikshit, Bhavishyanta, Chaitraratha, Muni and the celebrated Janamejaya.

95: And Puru had a wife of the name of Kausalya, on whom he begat a son named Janamejaya who performed three horse-sacrifices and a sacrifice called Viswajit.

Discrepancy 2:
94: And the sons of Janamejaya were all endued with great strength and became celebrated all over the world. And they were Dhritarashtra who was the eldest, and Pandu and Valhika, and Nishadha endued with great energy, and then the mighty Jamvunada, and then Kundodara and Padati and then Vasati the eighth.

And they were all proficient in morality and profit and were kind to all creatures. Among them Dhritarashtra became king. And Dhritarashtra had eight sons, viz, Kundika, Hasti, Vitarka, Kratha the fifth, Havihsravas, Indrabha, and Bhumanyu the invincible, and Dhritarashtra had many grandsons, of whom three only were famous. They were, O king, Pratipa, Dharmanetra, Sunetra.

Among these three, Pratipa became unrivalled on earth. And, O bull in Bharata's race, Pratipa begat three sons, viz, Devapi, Santanu, and the mighty car-warrior Valhika. The eldest Devapi adopted the ascetic course of life, impelled thereto by the desire of benefiting his brothers. And the kingdom was obtained by Santanu and the mighty car-warrior Valhika.

95: And upon her Santanu begat two other sons named Chitrangada and Vichitravirya. And before they attained to majority, Chitrangada had been slain by the Gandharvas. But Vichitravirya became king, and married the two daughters of the king of Kasi, named Amvika and Amvalika. But Vichitravirya died childless. Then Satyavati began to think as to how the dynasty of Dushmanta might be perpetuated. Then she recollected the Rishi Dwaipayana. The latter coming before her, asked, What are thy commands' She said, Thy brother Vichitravirya hath gone to heaven childless. Beget virtuous children for him' Dwaipayana, consenting to this, begat three children, viz, Dhritarashtra, Pandu, and Vidura.

Discrepancy 3:
94: The eldest of them, Ajamidha, was the perpetuator of the royal line. And he begat six sons, Riksha was born of the womb of Dhumini, Dushmanta and Parameshthin, of Nili, and Jahnu, Jala and Rupina were born in that of Kesini.

95: And Ajamidha had four wives named Raikeyi, Gandhari, Visala and Riksha. And he begat on them two thousand and four hundred sons. But amongst them all, Samvarana became the perpetuator of the dynasty.

Different Me's

you have skillfully illustrated the different approaches in analyzing the myths and explaining them. I am certainly not in favor of the blind acceptance or blind rejection. I am more inclined to an alien explanation though. Why can't the Devas, Gandharvas, Garuda be aliens? I think aliens interacted with ancient civilizations in India, Egypt, Atlantis etc.
