We are now in the first Vrat. So far we have had six Manvantras, and now we are in the seventh Manvantra.
In this Manvantra 27 Maha Yugas have passed already (about 1.96 billion human years).
At the same time, we are now in the first Charana of Kali Yuga, which means 5,100 years of Kali Yuga have passed, and another 426,890 years remain.
Interestingly, the oldest trace of life on Earth that scientists have discovered so far is 1.9 billion years old.
