I'm not defending anyone
I said it cannot be proven because it hasn't
you keep saying I don't understand evolution
clearly none of you do either because none of you have provided any evidence supporting your claim
Neat experiment in which E. coli developed the ability to metabolize citrate in aerobic conditions over thousands of generations of consistently maintained environment.
E. coli long-term evolution experiment - Wikipedia, the free encyclopedia
Although I'm sure you don't care because its still E. coli and not a fish, but the scientific community views this as strong evidence that evolution occurs in an observable timespan in microbial organisms. This is the equivalent of a race of people that are able to persist on a diet of rocks, or grass. shyt is really cool. Not people who turned into mermaids, though, so it probably doesn't count.
And for people who don't like to watch videos, a scientific theory is the simplest explanation for observed natural phenomena. Heliocentricism is a theory, Germ theory, the basis of nearly all modern medical practice, is a theory. Scientific laws are just equations.
Im also deeply troubled by the excessive use of the word proof. Science never proves anything. Math proves things. Science is a way of breaking complex observations down into comprehensible data. That is all. Never use the word proof in the context of a scientific discussion unless you want people to stop listening to you.
