Hindu "Science"

Sat-yuga: 17,28,000 years ago

Treta Yuga: 12,96,000 years ago ( Ramayana occured in this timeline)

Dwapar Yuga: 8,64,000 years ago (Mahabharat happened at the end of this era)

Kali Yuga: 4,36,000 years ago (Going on)

Problem: Arybhatta was born around 3rd century B.C and invented 0. So who counted those years of all of the above?

And as per evolution, homo sapiens came around 200,000 years ago. And just 30,000 years ago there were 3 species of human beings living together. Ice Age ended 10,000 years ago. No mention of it in any scriptures.

Also the yuga which majority hindus believe to be vile and evil i.e kali yuga, is a no brainer. According to many historians we are living in the most peaceful time in history. The reason they think that this is the worst time is probably because lower caste people now have voice and power to challenge the upper caste. Several centuries ago, that would have been impossibe.
