Yeah, but there are some people in the world that do understand things like nuclear fission. And they can explicitly see and quantify those results. Can't say the same for evolution.
I can't see nuclear fission, but I certainly understand the process.
However, I can see evolution.
Every day, I see babies being born, people dying, and life continuing.
That's evolution. No more, no less. It just happens in such small increments that our minds, capable of truly only fathoming timelines which max out at 100 years, cannot comprehend the development of a species over millions of those segments.
Yes, you are able to observe what's denoted as "microevolution". That is, you are seeing evolution or adaptation within a species. The origination of new species over long periods of time, (ie evolution on a large scale--macroevolution), is not and has not ever been observed.
And your definition of what evolution is lacks a very important aspect that is often overlooked and yet exceedingly important. Evolution, by its nature, requires
beneficial mutation of genes in an individual, while still allowing that individual to reproduce and pass along that gene. And, as one can guess, mutations are 99.99% of the time harmful to the host, resulting from radiation, or mistakes during meiosis in producing gametes.
So, what you observe is not "evolution" as most people understand it to be. It is merely the fluctuation of allele ratios in a gene pool of a species. No new alleles are arising.
