The One And Only Veronika

in science there are no "proofs". just verifications and falsifications of scientific theories. the legged fish are just another verification for the theory of evolution along millions of other facts discovered by scientists (fossils, cultivation of plants, breeding of animals etc.).
so of course there is no "proof" of the theory of evolution but there is an enormous amount of data verifying this theory und not a single observation in nature that falsify it (like i.E. a fossil of a cambrian poodle). If something like that would be observed the theory would be instantly obsolete and a new theory would be needed to explain the anomaly. but nothing like that was ever found so far so that the theory of evolution is pretty much one of the most well testet theories we have that make predictions about how different species evolve and allows a very well understood picture of how life on earth has evolved. (it does not explain how life began on earth btw. there are other scientific branches trying to explain that)

furthermore i have a question for you:
where is the evidence to verify your theory of "god still made that"? 

my problem is that this phrase "god did it" has been used very often in history to explain phenomena that couldnt be currently understand at various times:

"why there is lightning?"
"i cant explain that so god did it!"
*hint: electromagnetism*

"why do we get diseases?"
"i cant explain that so god did it!"
*hint: microorganisms*

"why .... so and so?"
"i cant explain that so god did it!"
*...*

as research progressed humanity found plausible answers to those questions because of the development and constant verification of scientific theories. the phrase "god did it" as an legitimate answer to questions evaporated as humanities knowledge expanded more and more (and it keeps expanding at an extreme speed).
it seems now that this "god" is just placeholder for "we do not know the answer" and is used by people who do not care enough to actually think about things and try to find out why things work such an such.

so if you think you have a plausible verifiable explanation of how "god did it" please feel free to show the world and get your nobel prize (you have to provide a plausible verification for the existence of god first btw). it has to be falsifiable and peer revievable for testing (thats how science works). if you can't provide that sort of evidence then a discussion of wether god did it (or even exists) or not is pointless because it then cannot make any verifiable predictions of value to humanity.

"Extraordinary claims require extraordinary evidence"
so the burden of proof lies by the people who make such claims
