this era is definitely not the right era for Buddha to
appear.
Let say, if Buddha did not appear in 2500 years ago, but is born
today in India, I wonder how Buddhism will begin from there.
This is a hypothetical question.
Buddha better appear 2500 years ago than now. People nowadays do
not have the same capacity and wisdom as those in the past.
Technologically wise we have grown, spiritually wise we have
degenerated, in terms of spiritual roots/capacity.
