the pipal tree has gone to other two religions and become the basic of the system

In Muntaka Upanishad of Hindu philosophy chapter third 
describes a symbolic story of two birds. One is adma 
(soul) and another is jeev(life). Both are sitting in a fig 
(ficus) (pippala) tree. Jeev eats the fruit of fig tree 
(Pippala) and adma(soul) is looking at her without any 
influence.. This story is told to explain even though 
the life (living being) is doing the worldly things 
(including sex) it will not affect the soul inside. 
The interesting thing in this story is comparison of 
the Adam and Eve of Bible with this. The following 
points are coincide. Adam and adma. Eve and jeev. 
pipple and bible. fig is fig (not changed). forbidden 
fruit is forbidden fruit (not changed).
Upanishads are 5000 years old. Bible is 2000 years 
old. Author Pippala (rishi) (hermit) was living 2500 
years ago. Jesus 2000 years. the pipal tree of the 
hindu religion has gone to christianity and islam
