"According to my good doctor, evolution isn't completely denounced in Islam as it is in Christianity, some aspects of evolution is in line with Quraanic thought like creatures coming from water originally."
Evolution is not something you can nit-pick, its all encompassing theory about the origin and evolution of all living things. To my best knowledge, Islam and christianity are totally at variance with the theory of evolution.
"Muslims do not however believe man and ape (dhuuso dere's ancestors)came from the same source."
What muslims believe is irrelevant. Objective historical facts are what we are trying to discern here. Personal opinions lacking supporting documentation are as convincing as a qabiilist preaching Islamic virtues.
"What Quran do reject is that Man is from apes. Because here in matters of Mankind Islam believes in Creationism."
So you believe the earth is 6000 years old and all humans descended from adam and eve shortly after the earth was created?

"And no there is no mention in the Quraan denying the existance of Dinosaurs."
Yah, but the quran says the earth is only few thousand years old and dinosaurse lived thousands of years ago. So in-born contradiction, don't you think?
"As the Quraan had said that there were other creatures which were created before mankind."
What creatures?
"And the Quraan also acknowledges the existance of other intelligent beings other than Mankind."
Like aliens?
"In Islam, Angels' sole purpose is to serve Allah without any question and the luxury of free-will."
There is no free will in the world of omniscient and omnipotent God with free will to create ONLY those he wants.
"Allah knows Best"
Unfortunetly, what Allah knows to be 'best' is of no value to us since he doesnt tell us PERSONALLY. Its something we have to figure out by ourselves.
