           HUMANS WHERE THEY COME FROM.??

QUESTION 1: Why does the evolution of human being had not seen  drastic changes in biological factors so far 200,000 years or about 50,000 years  full behavioral modernity(As human came from monkey then all the monkeys must have changed to humans !! and other organisms must have evolved too!!!) 

QUESTION 2:How does human brain is so powerful than other living creatures???

QUESTION 3:From where the first biological species came ???

==================================================================================================================================
  POSSIBILITY 1:  HUMAN BEINGS are species from other earth like planets which must be trillion light years away .They came out of their planets for survival and lastly reached earth as we search for a new planet in this universe.

            

*Figure:The spaceship is from some trillion light year far away from its home planet which reached earth    about 200,000 years ago..
Thus the spaceships landed on different regions in earth which lead to development of different civilization like EGYPTIAN,MAYAN and so on....


POSSIBILITY 2: Some alien species had fallen into earth due to its gravity or other reasons(space ship got crashed or soon).Then its sediment got mixed with this earth environment and organisms evolved. 

note: Apart from basic laws of nature there is possible how human evolved...!!
the thing is if transitions of organisms from one from to other is not largely seen in big organisms like humans...!!
