I agree we can observe mutations. but we have never observed one species of animal turn into a completely different species of animal.
saying that beneficial mutations through natural selection accumulate over thousands of years to form new species is a nice theory but you need to prove this is actually possible.
You should read about bacterial speciation, which is the only organism we can actually observe (and do observe) changing due to their fast generation time. And there is plenty of evidence for change over time both from the fossil record and comparison of DNA sequences between species split by geographical barriers with known ages.
