1000 scientist together cannot design a single piece of Human Brain.... then how is it possible that Brain evolved so perfectly in evolution?

It evolved, but evolution is never "perfect".  In fact, that's how it works.  When organisms reproduce there are little random errors all the time and sometimes those are useful. The useful errors get retained and the non-useful ones don't.  Over a VERY long time that results in great complexity, such as the human brain.

Doesn't work that way, but go ahead and make crap up to prove some point that you contrived.

Great argument but ... what happened with YOUR brain?

Right!  Whenever scientists can't do something, that's definitive evidence of the existence of God.  I mean, isn't that self-evident?  How can anyone argue with such a straightforward proposition?

If the brain is so perfect, how the hell can you explain trump's lunacy???
LMFAO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

you have no idea what evolution is and what it is not.

Really, it is matter of think but never get its right answer.!

Sounds to me that what you've effectively disproven is the concept of Intelligent Design:

"We cannot DESIGN this thing. Therefore, it follows that which of these two options is impossible:

A) It was designed
B) It was developed without design"


As a side note, if our brains are so perfect, how come so many of you cannot USE the damn things?

Scientists can create a computer that beats the human brain in chess and the game of Go as well as trivia games like Jeopardy. They human brain is not perfect. It took 3.5 billion years for the human brain to evolve. It only took scientists less than 100 years to create the super computer.

Survival of the fittest. Every piece of evolution is tested and if found defective, removed, (before any notification to anyone or thing) or adapted. The latter being in the minority.
Peace.
