From the word itself-evolution meaning to evolve or transform e di ba dapat alam natin na hindi makatuwiran ang theory of evolution? Kasi nga, uulitin ko lang, kung ang tao ay mula sa unggoy how come may nag-eexist pa rin na unggoy? E di sana kung nag-evolve ang tao from unggoy e di sana wala ng unggoy hindi ba?
Because humans came from a common ancestor as other members of the primate family did. Gorillas, chimpanzees and other kinds of the ape sub-species you'll see in the zoo.
Think of it this way, are dogs and wolves the same? They have a common ancestor, aesthetically, they look almost the same but genetically they are different.
Think of tigers, lions, cougars, panthers, cheetahs and include cats, they are all part of the feline family, they have a common ancestor yet they all vary in different genetic traits, behavior, social structure and physical traits. Feline families branch from here further to their respective categories.
If you apply the same concept to the species of order primates, we are a subgroup of homo-sapiens (from the word "Sapient" meaning, "the ones who are able to think"). We are the last known existing branch of the genus Homo which included other extinct species such as Homo Erectus and Homo Habilis.
Our niche in the animal kingdom is the ability to recognize patterns and incredible adaptability.
Kahit maghanap sila ng evidence, never ng mapapatunayan na totoo ang theory na yan kasi habang lalo silang nagreresearch mas lalo lang nakikita na mali sila at hindi posible yung theory.
The evidence is all around us, you can walk into any museum and do research, if you want to push it further, you can study genetics as well.
Ako kasi ay naniniwala sa theory of creation and I never doubted that. I believe in God.
Yun, marahil isa rin yun sa factor kaya nasasabi ng ilan na tama ang evolution dahil wala silang tiwala kay God or meron pa ngang mga atheist di ba? Sa sobra kasing talino ng tao ay minsan masyado kung mag-isip, yung parang akala lahat e aminin naman natin na imposible yun kasi imperfect tayo.
Well,
masyado akong nadala hihi 
There are plenty of arguments/debates already online about this, you can listen to debates by Richard Dawkins for a start. Listen to him with an open mind. I would also recommend Dr. Lawrence Kraus.
Remember, if you believe the bible story, since you follow the theory of creation, Adam and Eve had two sons, Cain and Abel, how can you propagate if there were no documented females in the bible during Cain and Abel's time? Who did Cain and Abel had sex with to propagate the species further?
Also, I've read an article that you need at least 23 couples for a stable DNA pattern since it prevents in-breeding. Can you explain how you can propagate to the huge variation we have (I.E. race & color) if we only started with such a small sample template?
