about how some of u ppl were xplaining science in a book xplains everything well, the holy texts r old and back wen they were written noone would've understood the scientific side of it.if it was written in the holy texts the holy texts noone would understand it. holy texts can b seen as to simplify the meaning of existence and dharma. the holy texts r looked to as sacred this is y the stories havent involved more science and even today most ppl wouldnt understand the science behind it.
