How likely is it that St. Thomas actually made it to India?

by ThanklessAmputation

Just got the CK2 achievement and then immediately saw an infographic about it on my front page, but do we have any evidence Thomas made it to India. I’m aware there are precolonial Christian communities in India, but how old are they? Finally how would a Judaean missionary make it all the way across Persia and into the subcontinent?
