"phenomenon and the theory" unfortunately, the meme is about "do you believe in evolution", so that already states my original statement... The "theory" is still called theory, but it has gone beyond that...
"Mathematics is the only field of study where something can be absolutely proven"
Wrong, on many accounts. That defies the very essence of many things being proven in the field of physics, were many things have already been absolutely proven without any possible way to debunk them. Physical laws are deemed absolute.... Like "energy cannot be created nor can it be destroyed", that is an absolute law, and it's not mathematics, so that debunks your very sentence, since what I just stated about energy is proven. Also even in mathemetics there are still a lot of unproven theories. Goldbach's theory for example is still unproven (He stated that every even number greater than 2 is the sum of two prime numbers). Of course the pythagorean theorism was proven by Pythagoras, although the formula itself predates Pythagoras by centuries, possibly even millennia. This shows that even in mathematics there are many things uncertain... And don't debate with me on that one... I am a coder, so I work with mathematics day in and day out.
And just like there are in mathematics still a lot of uncertainties, and loads of things are even subject of debate among experts in that field, so there are even in biology, in which most of its laws are not written in stone, like in physics, mathematics and chemistry, there are some things that are irrefutable. Yes, they make the minority, but still they are there. Evolution is one of those things, along with the rule of nature always trying to allow the fittest to survive (which is by the way also discovered by Darwin).
Mathematics is NOT the only field of study in which things can be proven irrefutably. And that is also a proven fact. And I can even give you a true fact by saying 1 + 1 = 10 ... The question is only how I made this to be true... People who are coders, like me, will see the trick I used. (I used binary, and that's how my formula became true). 1+1=2 is the simple math, but math has problems that even I who use mathematics every day cannot even begin to understand, since even the experts are in disagreement. And so biology also has its simple things. If somebody removes your eyes you cannot see... No way to debunk that one. If you lose your head, you'll die... Try to debunk that one... So yes, even biology has facts.
